[R] install packages automatically

[john seers (IFR)]

Hi 

I use the following method which works well for me.

I create a directory to hold the installed packages e.g. C:\Program
Files\R\mylibrary

Then in my C:\Program Files\R\R-2.5.1\.Renviron file I have a line as
follows:

R_LIBS=C:/PROGRA~1/R/mylibrary

(I think you have to use Windows short names in this file.)

Thus whenever I install a new package it is installed in this directory.
If I install a new version of R just update the .Renviron file and run
Packages->Update packages ...

This keeps the R base packages separate from the optional packages.

Subject: [R] install packages automatically

Dear Listers,
I am a little tired of installing all packages I want every time when I
instill a new version of R.
Say, if I have a list of packages I need to use, is it possible to tell
R to install them all for me automatically rather than I install them
one by one?
Thx.
