Thank you
removing everything and reinstalling while respecting every instruction did
not change anything...
evidently, I was too optimistic when thinking that the problem was caused by
something so simple... I continue to strive with it but, at least, I know
where not to look for the solution.

Dear Martin
thanks for your comprehensive instructions, had I found them earlier I
would
have saved at least 3 hours of problems...
Everyone copies: "your Windows system 'PATH' variable needs to be adjusted
once you've
installed graphviz and before installing Rgraphviz "
What if Rgraphviz is already installed? Trying every step proposed does
not
seem to work any more (I get "character (0)" when I try your check in R).
How can I remove Rgraphviz from R in order to start everything again? Or
are
there other solutions to that?
You can always reinstall via install.packages()
and if you really want to remove before, use remove.packages().

Thanks in advance
