R is command-line based. That means that every action taken by R has to be specified in a line of code, including downloading and loading packages.

To download a package, you would use

install.packages("packagename")

Make sure there are no spaces between the quotation marks and the name, R can be very literal, so for instance " package" is different from "package" as it has an extra space. After you install a package you still cannot use it until you tell R to load it using one of:

library(packagename)
require(packagename)

Note that quote marks are no longer needed at this point. If this is all so very confusing, might want to give R Commander a try.
