[R] Package Caret

It doesn't. namesraum = namespace which is technically different than
a paket = package (as you, as a German speaker, know of course). I
leave it to you to search for suitable references on the details of
what these are in R, unless someone wiser than I offers a
mini-tutorial here.

But glad I could help.

Best,
Bert
