You’re new to R? You don’t quite understand the code you copied from that tutorial? You get error messages that make no sense to you? Don’t worry, just askgpt!
askgpt is basically ChatGPT but from R (technically, it sends prompts
to OpenAI’s API directly from R). It also has
some additional functionality:
- Prompt “What is wrong with my last command?” (or “help!”) to get help on the last error R emitted
- Use the RStudio addin to comment, annotate or explain highlighted code
See more under Usage.
You can install release version of askgpt like so:
install.packages("askgpt")You can install the development version of askgpt like so:
remotes::install_github("JBGruber/askgpt")You can log into OpenAI’s API running the dedicated login() function
or just ask something with askgpt():
library(askgpt)
login()
#> ℹ It looks like you have not provided an API key yet. Let me guide you through the process:
#> 1. Go to <https://platform.openai.com/account/api-keys>
#> 2. (Log into your account if you haven't done so yet)
#> 3. On the site, click the button + Create new secret key
#> to create an API key
#> 4. Copy this key into R/RStudio
Copy the API key from OpenAI’s website
And paste it into RStudio
You will not need to do this again after the first time. (Technical
detail: This will store an encrypted version of your key in the
directory returned by rappdirs::user_cache_dir("askgpt").) If your old
API key does not work any more, you can store a new one with:
login(force_refresh = TRUE).
To enable error logging (which you need if you want askgpt to explain errors to you) first run:
log_init()After this, the key phrase “What is wrong with my last command?” (or
just “help!”) will make askgpt look up your last command and error
message and return some help for you. The other important key phrase is
“Can you elaborate on that?” (or just “What?”), which will elaborate
on the previous answer. You can ask basically any question you want
though:
examples.mp4
You can configure how askgpt makes that start with askgpt_*. For
example, to use a different model to use in askgpt() use
options(askgpt_chat_model = "gpt-3.5-turbo-0301") (or
options(askgpt_chat_model = "gpt-4") if you have beta access to the
newer model). If you use the completions instead of the chat API
(chat = FALSE in askgpt()) use
options(askgpt_completions_model = "text-curie-001"). It does not
matter if the API parameter is listed in the function or not. All are
used. See the complete list
here and
here.
The most important setting, however, is askgpt_config. This can be
used to configure the chat using plain English:
options(askgpt_config = "I'm 8 years old, please explain things easily")
askgpt("What is an R function?")

#> ── Answer ──────────────────────────────────────────────────────────────────────
#> An R function is like giving your friend a set of instructions to perform a
#> particular task. In R programming, a function is a set of instructions or steps
#> that is given a name, and when you call that name, the function will perform
#> those instructions. A function can take information or inputs, do something
#> with those inputs (like adding or subtracting), and then give the result back
#> as output.
#>
#> For example, think about giving your friend the instructions to make a peanut
#> butter sandwich. The instructions might be:
#>
#> 1. Take two slices of bread 2. Spread peanut butter on one slice 3. Spread
#> jelly on the other slice 4. Put the two slices together
#>
#> In R, a function might take a number (like 5) and add 1 to it, and then return
#> the result (which would be 6).
#>
#> Functions in R are used to make code easier to use, understand, and reuse. They
#> can also help programmers write complex and efficient programs.
