Ah, Martin! I know that "package" is the official terminology,
but R itself tempts the naive user into deviating from the
True Path. Indeed, I had my fingers burned by this myself,
a long time ago (I'm still licking them ... ).
One might ask: "Why do you think we use the function library()?"
when loading add-on packages into R. Indeed, the very directory
tree of R itself stores packages under /usr/lib/R/library.
So, once in a while, someone gets it wrong, and has to find it
out the hard way!
Best wishes,
Ted.
