Hi Martin,
thanks for your reply, and very thanks for your kind tips about "package"
and "library"
So, I was trying to understand *why* we load packages using library().
I suggest that developers killl the problem on its root, deleting library
function :-)
Good to know already installed packages will not be reinstalled.
cheers
