Thanks, Uwe
I have no way to test this and our IT people who do the installation
know nothing of R, so follow-up questions:
* There is no R_HOME/etc/x64/Renviron.site file, b
Just create it.
ut there is a
R_HOME/etc/Rprofile.site I can modify and
ask them to install. Would the equivalent in Rprofile.site be
Sys.setenv(R_LIBS_SITE="F:/R/library")
It maybe too late there, not sure.
* Does this require that the R_LIBS_SITE folder exist and be writable by
the user?
Well, you cann add several paths there separated by ";", I'd put a
stnadrd bapth for a per user library first that is writeble 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)"
Unless you have a writeable library in the first place as mentioned above.
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.
That depends oin your setup. On a non-tweaked Windows machie that
directory should be persistent.
Best,
Uwe
