Dear James,
I erroneously searched in the listserv for "Rgraphviz + allocate +
memory", which was the type of error I got. Since installation was not
giving errors I did not expect the error was linked to the lack of
installation of Graphviz.
Next time I will make a more deep search in the listserv.
I follow the instructions available in the link you provided and I
could load Rgraphviz without errors.
Many thanks!
Raffaele

Cheers
Raffaele
