Everytime I open a new session in RStudio, I'm greeted with the error message:
Error: C stack usage 7953936 is too close to the limit
Based on suggestions for similar issues posted here and here, I tried using the ulimit command in terminal, but get the following error.
Isabels-MacBook-Pro ~ % ulimit -s
8176
Isabels-MacBook-Pro ~ % R --slave -e 'Cstack_info()["size"]'
Error: C stack usage 7954496 is too close to the limit
Execution halted
Yet, when I run ulimit on it's own, I get:
Isabels-MacBook-Pro ~ % ulimit
unlimited
Just to double-check, I try setting it to unlimited again:
Isabels-MacBook-Pro ~ % ulimit -s unlimited
but then get a new error:
Isabels-MacBook-Pro ~ % R --slave -e 'Cstack_info()["size"]'
Error: evaluation nested too deeply: infinite recursion / options(expressions=)?
Execution halted
I have no clue what this means in this context. Is the Cstack_info() the bit getting stuck on infinite recursion?? I'd love to get this figured out, as it's getting in the way of installing some necessary packages!
In case it's helpful, here's my session info

Is there anything glaring here that could be causing the issue?
CodePudding user response：
Your user .Rprofile file is loading itself recursively for some reason:
if (file.exists("~/.Rprofile")) {
base::sys.source("~/.Rprofile", envir = environment())
}
From your comments it seems that these lines are inside ~/.Rprofile (~ expands to the user home directory, i.e. /Users/mycomputer in your case, assuming mycomputer is your user name).
Delete these lines (or comment them out), they don’t belong here. In fact, the file looks like it’s a template for a project-specific .Rprofile configuration. It would make sense inside a project directory, but not as the profile-wide user .Rprofile.
The logic for these files is as follows:
- If there is an
.Rprofilefile in the current directory, R attempts to load that. - Otherwise, if the environment variable
R_PROFILE_USERis set to the path of a file, R attempts to load this file. - Otherwise, if the file
~/.Rprofileexists, R attempts to load that.
Now, this implies that ~/.Rprofile is not loaded automatically if a projects-specific (= in the current working directory) .Rprofile exists. This is unfortunate, therefore many projects add lines similar to the above to their project-specific .Rprofile files to cause the user-wide ~/.Rprofile to be loaded as well. However, the above implementation ignores the R_PROFILE_USER environment variable. A better implementation would therefore look as follows:
rprofile = Sys.getenv('R_PROFILE_USER', '~/.Rprofile')
if (file.exists(rprofile)) {
base::sys.source(rprofile, envir = environment())
}
rm(rprofile)

Success! Thank you to everyone in the comment. The issue was resolved by deleting /Library/Frameworks/R.framework/Resources/library/base/R/Rprofile and re-installing R and Rstudio.
