[R] Help in installing packages

[Chetan Kumar]

Hi all,
My R installtion was fine till a few days back.
On trying to install a package I see this
"/usr/lib/R/bin/INSTALL: line 420: cd: src: No such file or directory"
I HAVE installed packages in the past without this kind of situation
having ever arisen.
To get around this I installed  R-1.8.1-2.i386.rpm again without
resolution of the problem.
Any suggestions ?
TIA
Chetan
