[R-sig-Debian] No internet connection

[Matthieu Stigler]

Obgos


I'm not expert and hope what I tell you is right...

There are two alternative ways to install a package, assuming you can
use apt-get (how did you install R?).

1 via apt-get (but don't know if the package you want is there, I'm
not on ubuntu machine now)
sudo apt-get install r-cran-cvt
check existing ones:
apt-cache search r-cran-*

2 What I did sometimes when I had proxy problems being in other places
was to install manually, it is rather a workaround but if you are in a
hurry that can help. Go to CRAN-packages, download the sources of the
package you want, go to the terminal and choose the directory where
the sources are (using cd), then:
R CMD INSTALL package
(maybe you need to install few more R package through apt-get such
as... mmh what is the name... r-dev I think)

Hope this helps
