R help - Nov 2023 - [External] Re: Error in setwd(dir) when initializing R

Hello,

Thank you all for your responses. When I initialize R, the folder in which
it starts is:

getwd()
[1] "C:/Users/Ana/OneDrive - Universidad Complutense de Madrid
(UCM)/Documentos"

So it seems a problem with OneDrive
-Kevin: I do not really understand your question... You mean if I set my
working directory to my C:// or D:// folder in my computer? It doesn't work
either.

-Ivan: this is the message I got when running traceback(). So can I move
the.Rdata file without affecting the work?

-Luke: thank you for the idea, I will try it.

Error in setwd(dir) : no es posible cambiar el directorio de trabajo>
traceback()4: setwd(dir)
3: .rs.onAvailablePackagesStale(reposString)
2: .rs.availablePackages()
1: .rs.rpc.discover_package_dependencies("3C994FEC", ".R")


Best,

Ana

This is something that RStudio (not R itself!) does, but it shouldn't
be failing. Here's what seems to be failing for you [*]:

   # prepare directory for discovery of available packages
   dir <- tempfile("rstudio-available-packages-")
   dir.create(dir, showWarnings = FALSE)

   # create a file in that directory
   saveRDS(Sys.time(), file = file.path(dir, "time.rds"))
   # (This doesn't fail because we keep executing the function, so the
   # directory must exist!) 

   # move there
   owd <- setwd(dir) # this somehow fails

Is it an option to disable OneDrive for the home directory? It's
clearly doing something terrible to your temporary files. If not, it
should be possible to create a separate temporary directory on your
computer (the path must not contain spaces) and list it in the
.Renviron file in the home directory as the TMPDIR variable:

TMPDIR=C:/my/R/temp/directory

See help(Startup) for more information on .Renviron.

Alternatively, we may try to perform some debugging. If you set
options(error = recover) and run .rs.availablePackages() again, it
should fail and give you a debugger prompt. Choose the deepest option
in the call stack and try to find out the value of the `dir` variable.
Does dir.exists(dir) still return TRUE? Does setwd(dir) still fail? Can
you open the directory in the Windows Explorer?

The last but not the least, do you see some of the same problems if you
launch Rgui.exe instead of RStudio?

This is likely tangential, but as a Linux user I have learned to avoid
any directory name with - or ( or ) or other things, even spaces. Whether or not
those are "valid", they seem to cause trouble.

For example "-" can be picked up in bash scripts as a trigger for
options.

And in this case, it looks like the OP does not have control of the name. Sigh.
