If you want to download automatically you need wget or lynx. You can find
wget at http://www.interlog.com/~tcharron/wgetwin.html

If you want to install a package you have downloaded separately you need
a) download the right package (the .zip binary, not the .tar source)
b) read the documentation of install.packages() to find out how to specify
a package file rather than a website: the file is the first argument to
install.packages() and the CRAN argument needs to be NULL.
