Why the need to install packages in root? As you are the only user there
is not reason to install them system wide (to make them available to all
users, which is just you). Installing the packages in your homedir
solves your problem much easier, without the need to run R as root
continuously. I think you should not run anything as root if it is not
absolutely needed, which could potentially damage your system
(accidentally overwriting something).
hope this helps,
