IT's probably not the problem of "get". Have you installed your
probepackage? Where did you install it in?
R will try to look online for the packge only when it thinks it's not
yet installed. This can happen when 1. it is indeed not installed or 2. it
is installed in a directory that R hasn't been told to look into.
