[R] Pb with RODBC installation

[pascal dessaux]

Hello

I'm starting to use R on a Windows XP Pro machine which is not connected to
the internet;

I want to use database connection so I downloaded the file "RODBC_1.0-4.tar"
from CRAN;

this file is not accepted by the
"Packages->Install Packages from local zip file" menu function of R!!!

I would like to know why it doesn't work and if it's possible to get
database connection on a windows machine?

Thanks you very much for your help
