[R] downloading packages at local disk

[Rodrigo Briceño]

Hi again R users. I was reviewing the manual of R about how to install
packages using the GUI and it's corresponding menu packages. My
question is how to download a specific set of packages in order to
install them in a computer that doesn't have internet access. Is there
a web page where I can search those packages? Basically I'm trying to
copy in a flash drive the packages MASS, BOOT and CAR.

Thanks for your help.
