Installation failed about powsimr

[bvieth]

Hello,

thanks for trying out powsimR!
So there appears to be an issue with the subversion (SVN).
If you successfully installed all dependencies of powsimR (see also https://github.com/bvieth/powsimR/issues/20#issuecomment-393850730), you can manually install powsimR:

Step 1: Download the source zip from github.
Step 2: Unzip the content.
Step 3: Run the following code (adjust the path as necessary):
library(devtools); source <- devtools::source_pkg("E:/temp/powsimR-master"); devtools::install(source); library(powsimR)

I hope this helps!

Kind regards
Beate

hi
i still get error message.

library(devtools); source <- devtools::source_pkg("C:/Users/gcrynen/Documents/powsimR-master"); devtools::install(source); library(powsimR)
Error: 'source_pkg' is not an exported object from 'namespace:devtools'

so I added one more : between devtools and source pkg and i get the SVN error.

library(devtools); source <- devtools:::source_pkg("C:/Users/gcrynen/Documents/powsimR-master"); devtools::install(source); library(powsimR)
Installing powsimR
Error: SVN does not seem to be installed on your system.

Hello,

One alternative is to download the zip file, unzip it and subsequently zip it as a tar.gz file and then install the source package in R:
install.packages("powsimR.tar.gz", type="source", repos=NULL)

Kind regards

Thank you for the advice, I hate to be the bearer of bad news but that didnt work either, here is the log

Hello,

so from your message above I can see that you have reached the maximum number of DLLs. As explained in the README file, you can set this system environmental variable to a higher number:

Starting with R version 3.4.0, one can set the environmental variable 'R_MAX_NUM_DLLS' to a higher number. I recommend to increase the maximum number of DLLs that can be loaded to at least 500. For that locate the Renviron file: First determine your R_HOME directory (see the output of R.home(component="home")), then in there, you will find the Renviron file in etc/ folder. Open the file with an editor and add the following line: R_MAX_NUM_DLLS=500. Save the changes to the file and restart your R to load the changes.

Kind regards
Beate

thank you for the quick reply. This helped me through installation but then when i loaded the package it gave me a similar maximum dll error. I looked at ?Startup file and reading that I created a "Renviron.site" file with the same line you suggested (R_MAX_NUM_DLLS=500) under the same etc folder (C:\Program Files\R\R-3.4.4\etc) and it worked!
thank you very much for all the help.
