What do I need to do to get "install.packages" to work properly for
me in R 2.9.1 under Vista?
Currently, install.packages in Rgui 2.9.1 by default goes to
"C:\\Users\\sgraves\\Documents/R/win-library/2.9". This is a problem
for me, because R running under Emacs does not currently look there.
I made the mistake last night of first installing R 2.9.1 in the
default "C:\Program Files". When I found that packages I installed
using Rgui could not be found from within Emacs, I uninstalled R from
"C:\Program Files" and reinstalled it under "C:\Users\sgraves\R"
alongside R 2.9.0, which has allowed "install.packages" from Rgui to be
accessed from R under Emacs.
I've traced the problem to the different behavior of ".libPaths()":
*** Rgui: .libPaths()
[1] "C:\\Users\\sgraves\\Documents/R/win-library/2.9"
[2] "C:/Users/sgraves/R/R-2.9.1/library"
*** R under Emacs: > .libPaths()
[1] "c:/Users/sgraves/R/R-2.9.1/library"
What do you suggest? Thanks,
Either set for the second setup
"C:\\Users\\sgraves\\Documents/R/win-library/2.9" as a default library
path (e.g. via env var R_LIBS) or remove it from the first setup (in a
personal startup file).
Best wishes,
Uwe
Spencer
