[R] Fwd: Rgraphviz installation problem

[Anton Gerostathos]

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.
Regards

Anton Gerostathos

You can always reinstall via install.packages()
and if you really want to remove before, use remove.packages().
