Dear R users,
I have a matrix with 2 columns with the variables: "daughter index", "mother
index". I would like to draw a network digraph using this data, where each
daughter is connected to a mother and between the connections inlcude a
circle with the information on the indices ("daughter index", "mother
index"): i.e. something similar to graphs produced by graphviz.
I am clueless. I have looked at the libraries SEM and SNA but it looks like
they can't help my cause.
Hope you help.

Since you mention graphviz, why not use Rgraphviz available from BioConductor? There are other packages available for doing graphing. A search of the r-help archives will turn up some discussion in the past 1-2 weeks. Sean

You want the Rgraphviz package from Bioconductor. To use Rgraphviz,
you will need to first install graphviz.
To install Rgraphviz:
If you are on a Linux type system with R-2.1.x:
source("http://bioconductor.org/biocLite.R")
biocLite("Rgraphviz")
If you use Windows, you need to use an R-devel snapshot in order to
(easily) access Bioconductor development packages (Rgraphviz was
only recently ported to Windows). But the commands to install are
the same as above.
HTH,
