[R] package installation problems

[allan clark]

Hi

I have tried to install some of the packages from the CRAN packages
section.

I am running  a windows system.

I did the following: (for example...)

   1.downloaded the zip file (mgcv_0.9-5.tar) from
http://cran.r-project.org/src/contrib/PACKAGES.html#sm
   2.and saved it in the library folder of R
   3.unzipped the file into the same folder
   4.a folder named sm was created
   5.from within R I loaded the package by using library(mgcv)

Any help would be much appreciated.
