> Dear all,
>
> I have a undirected network (g), representing all the sexual relationships
that ever existed in a model community.
> I also have a directed edgelist (e) which is a subset of the edgelist of g.
e represents the transmission pathway of HIV.
> Now I would like to superimpose the picture of the sexual relationships
with arrows in a different colour, to indicate where in the network HIV was
transmitted.
If you can't find an R answer, I've found that "dot" from
graphviz is really helpful. It should not be too hard to generate
the source code from your raw data file or R but others may have a more R
answer. Package sna may be helpful for
an R-only approach.
