Hi and thanks for suggestions. Based on these I installed acroread and
found that when viewed with acroread the Delta in the pdf file prints
out OK but when viewed with "evince", the document viewer, I get the
error. So, it seems not be an R issue at all. I am running 64-bit Ubuntu
9.10 for those who are interested in testing this.

Many thanks for all help.
