Hi there,
i am no way an expert user, so please bear with me, as i am basically
looking for a step.by.step tutorial to change pathes in R. This is my
current problem:
We are running R 3.0.2 with R-Studio on a Win7 environment. In our case,
the default working directory Users/Documents/R on the local drive is
not available. Instead, the path is redirected to a different network
drive (as all our profile data is stored on that H: drive). This used to
work fine at some point, but the other day, some major changes were made
to our server (which i have nothing to do with), and suddenly, a few
users having this problem:
Whenever i am starting R, i am welcomed with:
"Warning message:
In normalizePath(path.expand(path), winslash, mustWork) :
path[1]="//x/home$/tim/Documents/R/win-library/3.0": Access is denied"
And i am not allowed to install packages or manipulate objects in my
workspace. However, whenever i am running R with admin rights, i may
install packages, but they will be stored in a directory in
profiles/admin/appdata/local.
Curiously, when i perform .libPaths(), i get:
[1] "\\\\x/home$/tim/Documents/R/win-library/3.0"
[2] "C:/Program Files/R/R-3.0.2/library"
I can use the packages then with the normal user account though. Still,
i am not able to write into my workspace with normal user rights, and
for us, it is impossible to grant every user with admin rights to run
R-Studio.
From what i have found on google, there are workarounds for R, like
starting R from batch files, but i do not know if they're fine when i
want to start R from an GUI like R-Studio, too. I also have found advice
to change the path to the working and library location directory in the
Rprofile. I do find a rprofile.site in ../etc , but there is no path
given to the rprofile, which i think is needed. There was another tip to
manipulate R_LIBS_USER. But, tbh, there is a limit to my technical skill.
Do you have any idea to fix that issue? Or is anyone please willing to
give me a little guidance?
Thank you very much!
