Thanks for your quick responses, Gabor and Brian.

I'm currently running R version 1.9.1 on Linux. Actually, I have just tested this on R v.2.1.0 running under Windows XP, and indeed, as you both indicate, the problem does not exist on that version for that OS. So, at an appropriate time I'll upgrade my Linux installation to the most recent version (1.9.1 is a year old, I guess).
