  Well then, welcome.  You will need to spend a few minutes reading the posting
guide. Please make sure that you
   1) provide the output of sessionInfo() so we can figure out what version of
the software you are using
   2) provide a reproducible example so we can try it on our systems and
replicate the problem.

  best wishes
