Thanks very much for the this information Kasper. Unfortunately,
upgrading to R-2.9.0 is a largish job
because it entails upgrading some other packages that don't yet work
with 2.9.0 and modifying my
eclipse development environment as well. I was hoping to wait until
2.9.0-patched and other
packages settled down.
Because graphviz and Rgraphviz seem to have a long history of
incompatibility problems, could I suggest
that the DESCRIPTION file for Rgraphviz be more explicit about exactly
which version of graphviz it
was built with?
The present System Requirements,
Graphviz version >= 2.2
is insufficiently precise (I have Graphviz 2.20). Such information
could be also be maintained in an
Rgraphvis-package.Rd file, (with a link to
the graphviz version.) but that doesn't seem to be part of the package
That might forestall a lot of traffic on the bioc list on this topic,
though I realize it creates an extra
