tarchetypes
and not a known limitation, a usage error, or a bug in another package that tarchetypes depends on.I am using tarchetypes::tar_knitr_deps() to analyse the dependencies in an Rmarkdown file and discovered that it analyses a call to knitr::read_chunk() that is commented out.
test_report.Rmd
with contents:---
title: "test report"
output: html_document
---
```{r}
# knitr::read_chunk("non_existent_file.R")
```
tarchetaypes::tar_knitr_deps("test_report.Rmd")
in the console. (This assumes the working directory is set appropriately.)tar_knitr_deps()
tried to analyse the commented out call to knitr::read_chunk()
.Quitting from lines 7-8 (test_report.Rmd)
Error: Could not parse knitr report test_report.Rmd to detect dependencies: cannot open the connection
In addition: Warning message:
In file(con, "r") :
cannot open file 'non_existent_file.R': No such file or directory
I expected tar_knitr_deps("non_existent_file.R")
to return character(0)
because there is no executable code to contain dependencies.
It may be that tar_knitr_deps()
won't work with knitr::read_chunk()
, but I expected all code comments to be effectively invisible to `tar_knitr_deps().

Originally posted by ugoebel73 June 17, 2022
Our bioinformatics "targets" pipeline branches over the experimental contrasts of an input study (e.g., "treatmentA vs treatmentB") and is intended to render a separate output report for each contrast. Ideally any number of contrasts should be handled automatically.
tar_render_rep()
with default parameters fails if there is only a single contrast. However it does pass if parameter "branches" is set to 2. This can be traced back to the as.integer(cut(seq_len(nrow(params)), breaks = batches))
call in function tarchetypes::tar_render_rep_run_params()
: if nrow(params)=1, then this yields NA with batches=1, but 1 with batches=2.
I post this observation here because I am aware that tar_render_rep() is specifically meant for multiple output reports, so this behavior may not necessarily be considered a bug. However if tar_render_rep_run_params() could be made to handle the special case of a single report, this would simplify the handling of cases like ours, where the number of reports is not known in advance.
I have prepared a minimal example and could file a bug report if it is considered appropriate.
tarchetypes
and not a known limitation, a usage error, or a bug in another package that tarchetypes depends on.I'm using tar_render()
to knit a .Rmd report to Word using a reference template. Both the .Rmd and template.docx are in a doc/
folder. The .Rmd contains a call to flextable::flextable()
. When I click the "knit" button, or use rmarkdown::render()
everything works fine. When I use tar_make()
I get the error: Error : could not find file 'template.docx'
. This error goes away if I remove the call to flextable::flextable()
or if I move the .Rmd file and template.docx to the root directory of the R project.
I suppose it might be a bug with flextable
, but since it works fine with knit()
or rmarkdown::render()
I thought I'd post the issue here to see if you have any idea of a fix or workaround. I've tried specifying different paths to reference_docx
and can't seem to fix it. Other paths in the YAML work fine like csl:
and bibliography:

' code of conduct.tarchetypes

list(
tar_target(paths, c("a.csv", "b.csv")),
tar_target(files, paths, pattern = map(paths), format = "file")
)
We should define a new target archetype to condense this down to one line.
tarchetypes::tar_files(files, c("a.csv", "b.csv"))
tar_download()
could be a target factory that generates 2 targets: one format = "url"
target to track a group of remote URLs with , and a downstream format = "file"
target to download the URLs by running download.file()
on each one.
Limitations:
pattern
argument).Set the number of batches and partition evenly. Related: https://wlandau.github.io/targets-manual/dynamic.html#batching
Default tar_map()
target names are just numeric indexes when names
is NULL
. This means a target's validation status is sensitive to the ordering of values
(see reprex below). I propose we assign hash suffixes when names
is NULL
. It is a painful change that will invalidate some pipelines, sorry to say, but it improves the stability of pipelines in the long run.

tar_map(
values = list(x = c("a", "b")),
names = NULL,
tar_target(y, x)
)

# Switch the order of the values.

Check for the existence of *_files/
first. (It would be too brittle to inspect the source file and try to figure out if it is self-contained.)
What trouble are you having?
Is it possible to tar_map over a set of rmds?
reports <- tibble::tibble(outputs = c('report_a','report_b'))%>%
dplyr::mutate(
paths = sprintf("script/analysis/%s.Rmd",outputs)
)

values = reports,
names = 'outputs',
tar_render(period_report, paths,output_dir = 'deliv/reports')

Thanks for adding Quarto targets - I've been eagerly following the feature progress on this one! Ideally, tar_quarto()
would produce a similar error message to tar_render()
i.e. specify the lines/code chunk that produce an error (without needing to inspect tar_meta()
for quick debugging). Currently it just specifies that there is an error in the pipeline. MWE below altering the vignette example with a spelling error in the code chunk.
targets::tar_dir({ # tar_dir() runs code from a temporary directory.
# Unparameterized Quarto document:
lines <- c(
"---",
"title: report.qmd source file",
"output_format: html",
"---",
"Assume these lines are in report.qmd.",
"```{r}",
# Note the incorrect spelling to cause an error
"targets::tar_red(data)",
"```"
)
writeLines(lines, "report.qmd")
# Include the report in a pipeline as follows.
targets::tar_script({
library(tarchetypes)
list(
tar_target(data, data.frame(x = seq_len(26), y = letters)),
tar_quarto(report, path = "report.qmd")
)
}, ask = FALSE)

tar_render()
doesn't detect dependencies from calls to tar_load()
in the Rmarkdown file in some cases.
It works properly if the name of the target in tar_load()
is supplied as a symbol, but not as a character vector.
_targets.R
:
library(targets)
library(tarchetypes)
tar_option_set(packages = c("rmarkdown", "tidyverse"))
list(
tar_target(
sw_data,
dplyr::starwars
),
tar_render(
sw_report,
"sw_report.Rmd"
)
)
sw_report.Rmd
:
---
title: "test"
output: html_document
editor_options:
chunk_output_type: console
---
```{r setup, include=FALSE}
knitr::opts_chunk$set(echo = TRUE)
# Works:
tar_load(sw_data)
# Doesn't work:
# tar_load(names = c("sw_data"))
```
A plot of weight vs. height for characters in Star Wars (guess who's the outlier?)
```{r sw, echo=FALSE}
ggplot(sw_data, aes(x = mass, y = height)) +
geom_point()
```
The Rmarkdown file renders correctly when tar_load(sw_data)
is used:
targets::tar_make()
> tar_make()
● run target sw_data
● run target sw_report
But not when tar_load(names = c("sw_data"))
is used:
> tar_make()
● run target sw_report
Quitting from lines 9-16 (sw_report.Rmd)
x error target sw_report
Error : names arg of tar_load() must end up as character
Error: callr subprocess failed: names arg of tar_load() must end up as character
Type .Last.error.trace to see where the error occured
It should render correctly in both cases.

What trouble are you having?
I have a workflow with dynamic branching over endpoints in a model lets call it PARAMCD and have a parameterized Rmd that creates outputs based on params$paramcd. I would like to do something like tar_target(...,pattern = map(PARAM)), but it looks like tar_render isnt set up for this.
Is this correct?
Or am I looking at this function wrong?
here is the Rmd header
---
subtitle: "Predicting Something Amazing"
author: "Jonathan Sidi"
date: "`r Sys.Date()`"
output:
bookdown::html_document2: default
editor_options:
chunk_output_type: console
params:
paramcd: 'TOTAL'
title: "`r sprintf('Fancy title: %s',params$paramcd)`"
---
for now i have the data loading set up kind of awkwardly, but if i could iterate over the length of the target PARAMCD i could drop the use of this
```{r}
data_objs <- c('paramcd','model_data','model_train','lab_panels')
logistic_objs <- c('logistic_fit','logistic_best_fit','logistic_last_fit','logistic_best_workflow')
rf_objs <- c('rf_fit','rf_best_fit','rf_last_fit')
binom_obj <- 'binom_ci'
withr::with_dir(
rprojroot::find_root('_targets.R'),
targets::tar_load(all_of(c(data_objs,logistic_objs,rf_objs,binom_obj)))
)
```
```{r}
this <- which(params$paramcd%in%paramcd)
model_data <- model_data[[this]]
model_train <- model_train[[this]]
logistic_fit <- logistic_fit[[this]]
logistic_best_fit <- logistic_best_fit[[this]]
logistic_last_fit <- logistic_last_fit[[this]]
logistic_best_workflow <- logistic_best_workflow[[this]]
rf_fit <- rf_fit[[this]]
rf_best_fit <- rf_best_fit[[this]]
rf_last_fit <- rf_last_fit[[this]]
binom_ci <- binom_ci[[this]]

shows you this.Hi,
first of all thank a lot for the fabulous work you are doing, I was using slighly drake
(and actually posted a relevant issue that you solved.
Now I moved to targets
and I like it a lot. My workflow is to track new lectures/tutorials in dedicated folders and build a website for teaching. The part that is not working is how to deal with empty targets.
Here is a small example of something that is working, I am using tar_change
to track the apparition of new files, then we compute md5sum
and do stuff.
library(targets)
dir.create("tmp")
file.create("tmp/a")
#> [1] TRUE
writeLines("aa", con = "tmp/a")
file.create("tmp/b")
#> [1] TRUE
writeLines("bb", con = "tmp/b")
tar_script({
library(tarchetypes)
options(crayon.enabled = FALSE)
tar_option_set(packages = c("tarchetypes", "tools"))
tar_pipeline(
tar_change(x, dir("tmp", full.names = TRUE),
change = md5sum(dir("tmp", full.names = TRUE))),
tar_file(y,
setNames(x, md5sum(x)),
pattern = map(x)),
tar_target(z,
readLines(y),
pattern = map(y))
)
})
tar_make()
#> ● run target x_change

Now comes the issue, if we don't have any file in the folder, I get callr subprocess failed: cannot branch over empty target
.
To control for this, I tried to use tar_skip()
that seems to be relevant for this user case:
library(targets)
dir.create("tmp")
tar_script({
library(tarchetypes)
options(crayon.enabled = FALSE)
tar_option_set(packages = c("tarchetypes", "tools"))
tar_pipeline(
tar_skip(files,
dir("tmp", full.names = TRUE),
skip = !length(dir("tmp"))),
tar_change(x,
files,
change = md5sum(dir("tmp", full.names = TRUE))),
tar_file(y,
{
setNames(x, md5sum(x))
},
pattern = map(x)),
tar_target(z,
readLines(y),
pattern = map(y))
)
})
tar_make()
#> ● run target files
#> ● cancel target files
#> ● run target x_change
#> ● run target x
#> Error : cannot branch over empty target (x)
#> Error: callr subprocess failed: cannot branch over empty target (x)
Created on 2020-10-26 by the reprex package (v0.3.0)
I can see that the rule files
was indeed cancel as expected. But it didn't prevent the following steps to be processed.
I am a little lost now for preventing dependent branches to be performed.
Many thanks in advance for your kind help

(and drake
) are currently tied to traditional HPC (Slurm, SGE, etc.). That's enough for me and my team right now, but not for the increasing number of people like @MilesMcBain who rely on AWS and other cloud platforms. There is not yet much cloud support native to the R ecosystem, and since I don't use AWS for my own work, I am not prepared to do much at a low level.
Metaflow not only runs computation on the cloud and stores the results on S3, it also abstracts away the devops overhead that comes along with that, and it supports a sophisticated versioning system for code and data. I think we will gain a ton of power and convenience if we leverage Metaflow's rich and potentially complementary feature set in situations where targets
needs the cloud.
Earlier, I proposed a targets
-within-Metaflow approach, which I think would be useful for people with multiple {targets} pipelines in the same project. Here, I would like to explore the reverse: a target archetype that that runs some R code as a single AWS Metaflow step. Sketch:
# Archetype:
tar_metaflow(some_name, some_command(dep1, dep2), cpu = 4, memory = 10000)
# Equivalent to:
tar_target(some_name, {
metaflow::metaflow("some_name") %>%
metaflow::step(
step = "some_name",
metaflow::decorator("batch", cpu = 4, memory = 1000),
r_function = function(self) self$some_name <- some_command(dep1, dep2)
) %>%
metaflow::run()
download_artifact_from_aws("some_name") # needs to be defined
})

The warnings indicated the non-ASCII characters are not recognized. Is there a method to get rid of it? Or this function tar_render()
should be updated?
tarchetypes
and not a known limitation, usage error, or issue from another package that tarchetypes
depends on. If you are unsure, please submit a discussion thread instead.When try to render a {distill} article using tar_render
, it will be correctly rendered, but it returns a strange error:
> targets::tar_make()
* start target report
x error target report
* end pipeline
Error : Distill articles cannot be previewed in this version of RStudio.
Please update to version 1.2.718 or higher at https://www.rstudio.com/products/rstudio/download/
Searching the web, I have discovered this discussion reporting the same issue (even if I can create the HTML report, which is rendered!)
The issue seems related (as stated in an answer to that SO thread) to a missing environmental variable. As suggested, I have also tried rmarkdown::render("distill_target_test.Rmd")
, which correctly renders without any error (nor preview...)
My verions are:
OS: Windows 11 Pro for Workstations 21H2
R: 4.1.2
RStudio: 2021.09.0 Build 351
{targets}: 0.8.1.9000
{tarchetypes}: 0.3.2.9000
{distill}: 1.3
Involving an environment, I have set-up a minimal renv-project at CorradoLanera/targets_distill. Just clone and run run.R
.
So the main problem is that the error invalidates the network, resulting in an errored node. As I said, the report is rendered!
Do not receive an error, or at least the option of safely ignoring it with no invalidation of the DAG's node for the report.

currently installedStarting to learn targets and migrating from drake so not sure if I'm doing things right but I cannot get the naming right when trying to run tar_map()
over a list of vectors:
targets::tar_dir({ # tar_dir() runs code from a temporary directory.
targets::tar_script({
list(
tarchetypes::tar_map(
values = list(a = list(c("foo", "bar"), c("test1", "test2"))),
names = c("first", "second"),
targets::tar_target(b, paste(a, collapse = "-"))
)
)
})

# A tibble: 2 x 3

<chr> <chr> <chr>
1 b_1 "paste(c(\"foo\", \"bar\"), collapse = \"-\")" NA
2 b_2 "paste(c(\"test1\", \"test2\"), collapse = \"-\")" NA
Seems targets are assigned numbers instead of values from the vector of names. If I remove the names it calls the two targets "foo" and "bar" but each target still has the intended content. Would have expected the second target to be named "test1".

1 b_foo "paste(c(\"foo\", \"bar\"), collapse = \"-\")" NA
2 b_bar "paste(c(\"test1\", \"test2\"), collapse = \"-\")" NA
Also, trying to add pattern = map(a)
to the target produces Error : x must not be empty
.
#41 shows how a time based invalidation could happen:
tarchetypes::tar_force(index, seq_len(4),
force = if (file.exists("_targets/objects/index")) as_date(file.info("_targets/objects/index")$mtime) < (lubridate::today())
)
I wonder if it would make sense to add some time-based convenience options to force
to simplify achieving this and improve readability.
tarchetypes::tar_force(index, seq_len(4),
force = "daily"
)
tarchetypes::tar_force(index, seq_len(4),
force = "weekly"
)
Not sure what is happening behind the scenes and if this is possible in the first place but it would help a lot :)
tarchetypes
' code of conduct.tarchetypes
' contributing guidelines.Just like tar_render()
, but for knitr::knit()
.
Short version: Can tarchetypes::knitr_deps()
or something similar be exposed to the user to provide a list of symbols of targets in an Rmd file?
I use bookdown to create notebooks. Different weeks get their own chapters (.Rmd files) and then they all get stitched together into a single html file. drake/targets handle the backend data construction and modeling and these analysis objects are loaded into the chapters. The whole book is regenerated if any of the dependencies are changed.
tar_knit()
and tar_render()
don't help me here because they are designed for single document knits and they make different assumptions. That's fine. The book is compiled with render_site()
which is a different function than knit() or render(). So instead I provide a block of commands the will connect the book to Rmd files (in case prose changes) and to a list of targets (in case data changes). It looks like this:
# build the notebook
tar_target(
notebook, {
extra_targets = rlang::list2(!!! results)
notebook_rmd_paths # defined in a different target
notebook_files # defined in a different target
rmarkdown::render_site("notebook", encoding = 'UTF-8')
here::here("notebook/docs/notebook.html") # target file
},
format = "file"
),
where results
is a list of symbols of things that are tar_read()
or tar_load()
in each file. To get results, I had to make a function that crawls overs the Rmd files and pulls out tar_read()
and tar_load()
files. I'm asking whether this package might provide the function it uses for this purpose.

and not a known limitation, usage error, or issue from another package that tarchetypes
depends on. If you are unsure, please submit a discussion thread instead.When tar_age
is used with static branching, targets are always run. The help only mentions the interaction with dynamic branching. I would have thought it would work because the generate targets are just normal tar_age

No artifact target should appear.
To clean up some function cloning technical debt (related: https://ieeexplore.ieee.org/document/7069885) I just exported targets
' error handling and metaprogramming utilites:
https://docs.ropensci.org/targets/reference/index.html#section-extending-targets. tarchetypes
should use them. Need to wait until after version 0.2.1 is accepted on CRAN though.
From @liutiming, ropensci/targets#329.
tar_rep()
establishes a batching scheme, but then it is up to the user to write custom code to iterate over reps within batches. If possible, it would be nice to have a helper automatically process the iterations of an individual batch. This sort of thing is so general that I am not sure it is possible Sketch:
# _targets.R
library(targets)
library(tarchetypes)
list(
tar_rep(data1, simulate_data(), batches = 40, reps = 25),
tar_rep(data2, simulate_data(), batches = 40, reps = 25),
tar_rep(data3, simulate_data()),
tar_target(analysis, tar_map_reps(analyze_data(data1, data2, data3)), pattern = map(data1, data2))
)
tar_map_reps()
should automatically detect which targets are batched (e.g. data1
and data2
but not data3
) and infer how to iterate over the batches given the data types (lists or data frames).
targets
is amazing and I'm so impressed with what you've done here. Congratulations on such a great package!

Different intermediate_dir
should be passed to rmarkdown::render()
in order to avoid the concurrent removal of intermediate knitr files. My suggestion: for intermediate_dir
use basenames of output_files
or create random-named directories.
Thanks in advance for looking into this! For now, I have to run the pipeline sequentially with tar_make()
to avoid this problem.
tarchetypes
' code of conduct.tarchetypes
' contributing guidelines.Here in the targets-stan
example, we batch simulated datasets in order to avoid egregiously large numbers of targets.
tar_pipeline(
tar_target(
index_batch,
seq_len(2), # Change the number of simulation batches here.
deployment = "local"
),
tar_target(
index_sim,
seq_len(2), # Change the number of simulations per batch here.
deployment = "local"
),
tar_target(
data_continuous,
map_dfr(index_sim, ~simulate_data_continuous()),
pattern = map(index_batch),
format = "fst_tbl"
),
...
)
This technique is good practice in simulation studies, and I want to make it easier to use. I propose new target archetypes to help. The above could simplify down to this:
tar_pipeline(
tar_rep_tbl(data_continuous, simulate_data_continuous(), batches = 2, reps_per_batch = 2)
)
Proposed archetypes:
Non-standard evaluation | Standard evaluation |
---|---|
tar_rep_list() |
tar_rep_list_raw() |
tar_rep_df() |
tar_rep_df_raw() |
tar_rep_tbl() |
tar_rep_tbl_raw() |

' code of conduct.tarchetypes
' contributing guidelines.From ropensci/targets#130 and ropensci/targets#131, cc @noamross and @jaredlander.
There are really two logical ways to think about the condition
trigger:
TRUE
, otherwise defer to other triggers.FALSE
, otherwise defer to other triggers.Since these thought processes are different, the archetypes should also be different.
tar_suppress(dataset, download_data(), suppress = file_is_recent())
tar_force(dataset, download_data(), force = file_is_old())
I have not quite worked out how best to implement this, but I do think branching should be prohibited here.
Check the age of the target using tar_timestamp()
and rerun the target if it is old enough (according to a user-supplied difftime
object). This pretty much just requires a custom tar_cue()
with mode
equal to "always"
or "thorough"
, depending on when the target last ran.
I don't think we can support dynamic branching in this one. Cues operate on all branches at once, but tar_timestamp()
is branch-specific.
tarchetypes
' code of conduct.tarchetypes
' contributing guidelines.A plan is a pipeline archetype where most targets are simple and require no extra config. The proposed tar_plan()
is like tar_pipeline()
, but it will support the simpler target = command
syntax in drake
plan for named arguments. Unnamed arguments will assume the target is fully already specified with tar_target()
. cc @MilesMcBain.
The following are equivalent:
tar_plan(
tar_target(
raw_data_file,
"data/raw_data.csv",
format = "file"
),
raw_data, read_csv(raw_data_file, col_types = cols()),
data = raw_data %>%
mutate(Ozone = replace_na(Ozone, mean(Ozone, na.rm = TRUE))),
hist = create_plot(data),
fit = biglm(Ozone ~ Wind + Temp, data)),
tar_render(report, "report.Rmd")
)
tar_pipeline(
tar_target(
raw_data_file,
"data/raw_data.csv",
format = "file"
),
tar_target(
raw_data,
read_csv(raw_data_file, col_types = cols()),
deployment = "local"
),
tar_target(
data,
raw_data %>%
mutate(Ozone = replace_na(Ozone, mean(Ozone, na.rm = TRUE)))
),
tar_target(hist, create_plot(data)),
tar_target(fit, biglm(Ozone ~ Wind + Temp, data)),
tar_render(report, "report.Rmd")
)
tar_target()
calls.tarchetypes
since we don't want to bother targets
with it and we don't want to make users load 3 different packages just to get the full interface. But we do need to be careful about how we define tarchetypes
' scope. It can support DSLs too, but we need to be clear that it is more about overall shorthand than just target-by-target helpers.Batched dynamic-within-static branching for data frames comes up a lot. stantargets
and jagstargets
alone have several examples. I think we can create a target factory to generalize the idea.
tarchetypes
' code of conduct.tarchetypes
' contributing guidelines.Let's create new functions tar_map()
, , and tar_cross()
tar_combine()
to replicate static branching from drake
. Each should accept one or more existing tar_target()
objects and produce a list of tar_target()
objects. Example:
tar_map(
tar_target(x, a),
tar_target(y, a),
args = list(a = c(1, 2, 3))
)
This should be equivalent to:
list(
tar_target(x_1, 1),
tar_target(x_2, 2),
tar_target(x_3, 3),
tar_target(y_1, 1),
tar_target(y_2, 2),
tar_target(y_3, 3)
)
It will take some extra work and care to preserve the branching settings of the original targets. Need some extra tests for that.
tarchetypes
' code of conduct.tarchetypes
' contributing guidelines.https://github.com/wlandau/targets/labels. I wish I knew an automated way to copy over all these labels.
In README.Rmd, you reference tar_plan()
, but the accompanying example doesn't use tar_plan()
; rather, it uses tar_pipeline()
. I think that's a mistake?
I think you could also change the first target to a tar_file()
, if you wanted to?
Thanks for a great package, and all the contributed talks lately!
To make sub-projects easier, I am thinking about a new tar_import()
target factory to import a target from another local pipeline. The idea is to depend on the data hashes in the _targets/meta/meta
from the other pipeline, then tar_read()
the targets from that other pipeline. tar_import()
would copy the files, which duplicates storage, but is preferable because it allows the current pipeline to do some exploratory stuff even the other pipeline breaks, and it also lets the user set a different storage format etc. for the imported target in the new pipeline, as well as give the imported targets new names in the new pipeline.
This is similar to @nsheff's unitar
package except tarchetypes::tar_import()
will be able to handle dynamic branching (and optionally select branches to import) by mapping over the data hashes in the other pipeline's metadata.
Automated hooks could let users prepend or wrap arbitrary R code around all the commands of all the targets in a target list. This could solve a multitude of issues, including:
conflicted
setup (cc @MilesMcBain)tar_hook_before()
# Regular _targets.R
library(targets)
source("R/functions.R")
list(
tar_target(x, {
set_up_conflicted_package()
do_work()
}),
tar_target(y, {
set_up_conflicted_package()
do_more_work()
})
)
# _targets.R with tar_hook_before()

targets <- list(
tar_target(x, do_work()),
tar_target(y, do_more_work())
) %>%
tar_hook_before(set_up_conflicted_package)
tar_hook_inner()
and tar_hook_outer()
# Regular _targets.R
library(targets)

list(
tar_target(data, encrypt(get_data())),
tar_target(analysis, encrypt(analyze(decrypt(data))))

source("R/functions.R")
targets <- list(
tar_target(data, get_data()),
tar_target(analysis, analyze(data))
) %>%
tar_hook_inner(encrypt(.x)) %>%
tar_hook_outer(decrypt(.x))
tarchetypes
' code of conduct.tarchetypes
' contributing guidelines.From ropensci/targets#130 and ropensci/targets#131, cc @noamross and @jaredlander.
tar_change(dataset, download_data(), change = remote_hash(dep1, dep2))
list(
tar_target(dataset_change, remote_hash(dep1, dep2), cue = tar_cue(mode = "always")),
tar_target(
dataset, {
dataset_change # Enforces the dependency relationship
download_data(),
}
)
)
Patterns/branching should be disabled.
Doesn't seem like much of a change to me, but user feedback suggests this is likely to simplify things for others.
tar_plan()
now returns a target list instead of a pipeline object. As of ropensci/targets#254, _targets.R
files should end with lists of targets instead of pipeline objects. tar_pipeline()
and tar_bind()
still work but are now deprecated. The return value of tar_plan()
has changed but should still work for most use cases. Logging this issue for reference.
Currently, tar_map()
is a helper function to build static branches, but it does not have a pattern
argument. I think this could be added in order for a better combination of static and dynamic branches.
tarchetypes
and not a known limitation, usage error, or issue from another package that tarchetypes
depends on. If you are unsure, please submit a discussion thread instead.Thanks for the great package ecosystem! Sorry if I am misunderstanding anything here.
tar_select_targets()
returns incorrect targets when they are not in alphabetical order. In the reprex below, I slightly modified the example in the tar_select_targets()
help file, to change the order of targets within the targets

I think that the issue comes from the sort()
function in this line:

Line 29 in d8bded8
library(tarchetypes)

The returned targets should not depend on how the targets are ordered in the input list. I think that simply removing sort()
from the function fixes the issue (see reprex below), but I might be misunderstanding its role?
Thank you!
