Documentation for reg.finalizer

Documentation says (emphasis mine):

"Registers an R function to be called upon garbage collection of
     object OR (optionally) at the end of an R session."

Should this say "and" and not "or"?

THK

No.  "Or" in English is in the context the "inclusive or", not the
"exclusive or".  The function will only be called once, either when the
object is garbage collected, or (if the option is selected) at the end
of the session.
