[R] install pls.pcr package

[Dowkiw, Arnaud]

How do you install a package from CRAN ? I want to install pls.pcr, so I have downloaded pls.pcr_0.1.1.tar.gz  but when I try to install it using the install package(s) from local zip file(s) option it says : 

> install.packages(choose.files('',filters=Filters[c('zip','All'),]), .libPaths()[1], CRAN = NULL)
Error in file(file, "r") : unable to open connection
In addition: Warning messages: 
1: error 1 in extracting from zip file 
2: cannot open file `pls.pcr_0.1.1.tar.gz/DESCRIPTION' 

Thanks a lot,

Arnaud
