I'm the faculty member in my department who advises our IT staff on the
details of installing R for
students and faculty on our Windows 7 lab network. We are about to
upgrade from R 3.1.1 to
R 3.2.1, and once that is done, this version of R and all installed
packages will be frozen in the
image that appears in C:/Program Files/R/R-3.2.1/ on every lab computer,
and this image is
refreshed on each computer at each new login.
Every user has a persistent home directory across all university lab
computers, typically their
F:/ drive (students) and/or X:/ drive (faculty). I need to give
instructions to our IT staff for how to
arrange for a personal library, say
F:/~R/library
to be be set automatically, and included in .libPaths() so that
install.packages() and update.packages()
will work using that path.
At present, there is no file R_HOME/etc/Renviron.site and
R_HOME/etc/Rprofile.site is the vanilla
version with everything commented out, including
# set a site library
# .Library.site <- file.path(chartr("\\", "/", R.home()),
"site-library")
Environmental variables set for users include
HOMEDRIVE=F:
HOMEPATH=\
HOMESHARE=\\vfadmin.yorku.yorku.ca\HH\HOME\friendly
with the latter mapped to the X: drive
What is the code to be added to Rprofile.site to make this work?
thanks,
-Michael

Just add the line R_LIBS_SITE=F:/R/library to the file R_HOME/etc/x64/Renviron.site Best, Uwe Ligges On 28.07.2015 15:53, Michael Friendly wrote:> I'm the faculty member in my department who advises our IT staff on the > details of installing R for > students and faculty on our Windows 7 lab network.

Would the equivalent in Rprofile.site be Sys.setenv(R_LIBS_SITE="F:/R/library") * Does this require that the R_LIBS_SITE folder exist and be writable by the user? Here is what I see in the current version: .libPaths(), the library trees where R looks for packages gives: [1] "G:/uitapps/HEBB_R_LIB2/library" [2] "C:/Program Files/R/R/R-3.1.1/library" If I try to install a new package, e.g., install.packages("rockchalk") I get "G:/uitapps/HEBB_R_LIB2/library is not writeable. Use a personal library instead?", followed by a popup window, "Create ~R/library? (y/n)" This then installs the package, but to "C:/Users/friendly/Desktop/~R/library". In the current login session, .libPaths() will then have this path, so in a new R session, load(rockchalk) will work. However, once I logout, all that disappears, so I have to start over again to install or update a package. -- Michael Friendly Email: friendly AT yorku DOT ca Professor, Psychology Dept. & Chair, Quantitative Methods York University Voice: 416 736-2100 x66249 Fax: 416 736-5814 4700 Keele Street Web:http://www.datavis.ca Toronto, ONT M3J 1P3 CANADA
