thank you! I just found it out myself by looking at

Which brings me back to the core of my question: Where was I supposed
to find this piece of information myself. The logical place, in my
opinion, would be Section 11.3 of "An Introduction to R". Am I missing
something here? If desired, I can write a patch for R-intro.texi.

                       from such a trifling investment of fact.
