Hello- I am trying to download packages from CRAN to my Window-based system. I downloaded the most recent version of Perl, as instructed in the Install Manual and the "car" package, just as a trial. Where should they "reside" within my computer: the unzipped Perl I have placed at ...R/rw1070; the "car" package I unzipped and placed at ...R/rw1070/library. Is this correct? I have tried calling various commands via help(...) as a proxy to see if the commands / functions are available [perhaps this is incorrect?] and get the message,"No documentation for ... in specified packages and libraries"... I think my problems are related to the fact that I have mis-addressed or mis-ordered something. Am I right? I greatly appreciate all of the help I've receive to date -- thanks for your continued patience. A good weekend to all. Rick

I don't think you need Perl to download packages from CRAN, nor do you need to have Perl installed to to be able to install new package. How did you download the packages? The easiest way is probably to do it within Rgui. In the menu bar go to Packages -> Install packages from CRAN..., and select the package(s) you want to install. The installation is automatic and the package(s) will be unpacked to the correct place.

Provided you installed the package(s) properly, have you loaded it before calling the documentation? Using the car package example: > library(car) > ?box.cox seem to work fine.
