Packages can be installed or updated using the
install.packages function, which will connect to a CRAN
repository on the Internet and download the package. If no repository
has already been specified, R will request one to use. You can
specify one using the options function. Your installed
packages will be updated using the update.packages
function, while packages can be removed using
remove.packages.
> options(repos="http://cran.us.r-project.org/")
> install.packages("ellipse") # Installs the ellipse package from CRAN.
> install.packages("H:/ellipse_2.0-14.zip", repos=NULL)
> update.packages()
> remove.packages([...])

You can identify the status of the packages you have installed in your R system with packageStatus. You will be asked to select a CRAN mirror from which to retrieve information about the available packages.

If you then request a summary of the packageStatus you will get details about the packages, including, for example, those available from each of the local libraries, identifying those that have upgrades available.
