Help us to help you, Gallon. Which error comes out?

Of course, on a normal installation R need to be run by root to do
this, in order to write in a "system" directory like /usr/lib/.

Again, the user running R must have writing access to the directory
specified by the 'lib' option. This option allows to install R
packages in a directory in your /home, typically.

Maybe you want to try (dependencies=TRUE) to automagically download
and install dependencies.

And of course you downloaded the appropriate package for you R version.
