Michael, thanks, that was it!
I had installed the packages as root and tried them out as root (not a good
idea I know, but I was lazy), while running the the X11 display as user.
Worse is that I have done that many times. One more thing learned.
Thanks again,
Rainer

Perhaps this is a permissions (Xauthority) issue: is the same user running
both the X11 display and the R session?
