Goran is correct that you need to run R INSTALL at the shell prompt.
If you want to install the library in a private collection you can add
the -l flag to specify the location of the library.  You should then
establish an environment variable R_LIBS as a colon-separated list of
directories in which to look for libraries.

The call to R INSTALL would look like

R INSTALL /usr/apps/tree -l ~/.Rlibs

or something like that.

Note that with recent versions of R you do not need to expand the tar
file.  You can give the name of the tar file to the INSTALL command.
