"neato" allows you to set several edge attributes, a close one to what
you
want is "style", which could be solid/bold/dotted/dashed. It seems
that
currently only "solid" works well.

I don't think there is any easy way to achieve this in the current
released verison of Rgraphviz. However, in the devel version, code
has been added to allow specifying lwd (width) and lty (type) for the
edges.
To use this feature, one needs to add lwd and/or lty members to the
edge attributes list (your eAttrs below).
