renv 1.0.2 Error in if (n == 1) word else paste(word, "s", sep = ""): app[web.1]: the condition has length > 1 about heroku-buildpack-r HOT 4 CLOSED

Due to the constraints of Heroku, all project files together with the R runtime, configurations and cache directories are all located within the /app directory (which is also the home directory).

As a result, when R starts and .Rprofile sources the renv/activate.R script, renv fails while searching through all the R files found within these directories.

Adding a .renvignore file to the project root directory to exclude these directories resolves the issue.

# .renvignore
.cache
R

Hi @DaboinCJ

Were you able to run your application with the changes suggested?

Hi @virtualstaticvoid, thanks for digging deep into this, I appreciate it.

I made the tool work with an init file instead, so I haven't tried that solution yet. I'll try next week.

I bypassed the problem by using the init file again and installing the exact version I needed for a couple of problematic libraries from packagemanager.posit.co.

Hi @DaboinCJ

Apologies for the delay in responding.

Unfortunately, I haven't used recent versions of renv with the buildpack, so I haven't encountered this issue.

Reading the post you linked and follow up comments, the issue seems related to the existence of the renv cache directory.

I'll attempt to replicate the issue and revert back.
