Error in if (n == 1) word else paste(word, "s", sep = "") : the condition has length > 1

I have a project with renv 1.0.2. It seems to work fine in one environment, but inside a docker image it generates the following error when R is starting:

renv::restore()

$ Rscript -e 'renv::restore()'

I tried to add the following lines to the beginning of the .Rprofile:

options(error = renv:::renv_error_handler_call()); options(warn = 2L); "

Then the error looks like this (no change, it seems):

Are you able to share the contents of your bookdown project? This error:

Error in if (grepl("-display$", label)) return(TRUE) : 
  (converted from warning) the condition has length > 1

seems to imply you have a chunk with multiple labels, or that renv failed to parse the label in one of your chunks.

[idavydov]

It took a bit of time to debug this.

Turns out, I forgot to include renv cache directory to .gitignore. Since the thing was running inside CI, it's quite common to have CI directory as a sub-directory inside the repository. So renv was searching for dependencies across several hundred cached packages.

Now the questions are:

• Is it worth it so search which file broke renv dependency search?
• Or would it be maybe more useful to report a file where parsing broke?
• Maybe renv could automatically exclude the cache directory from search?

[kevinushey]

Thanks! Maybe renv should drop a .renvignore file in the cache directory?

[idavydov]

.renvignore in the cache directory seems like a great idea to me.

Hi @idavydov,

I'm getting the same error message while deploying a Shiny App to Heroku 20 using Heroku buildpack-r.

Can you describe how you solved it? What changes did you make to the .gitignore?

Thank you

[idavydov]

hi @DaboinCJ , in my case library cache location was set up using:

RENV_PATHS_CACHE: "$PROJECT_DIR/ci/renvcache"

So I simply added ci to .gitignore to make sure that renv doesn't scan the cache.

Does that help?
