[Fwd: Re: controlling the edge linewidth in Rgraphviz]
Hi Adrian,
even better would be this:
1.) Install the latest Rgraphviz devel version
2.) Use the new API for graph rendering:
library(Rgraphviz)
example(randomEGraph)
x <- layoutGraph(g1)
graph.par(list(edges=list(lwd=2))) # if you want to set lwd=2 for the
whole session
# or if you just want to change this for your one graph:
renderGraph(x, graph.pars=list(edges=list(lwd=2)))
There is a

Rgraphviz - neato layout - edge weights do not have an effect
Dear all,
neato makes layouts according to a physical model in which the length of
the edges is determined by springs. The weight of the edge is the
strength of the spring. However, I was not able to find any influence of
edge weight on the layout. In the
http://www.graphviz.org/Documentation/neatoguide.pdf the attribute "len"
is another parameter of the neato layout.

controlling the edge linewidth in Rgraphviz
Hello,
I would like to have different linewidths for the edges of my graph. I
read the documentation but could not find how to control this. On the
Graphviz help page I've seen that there is something called "penwidth" but I
could not find it in the R edge attributes.
Thanks a lot for any help.

Dear people,
I'm new here, so this is my first try.

I have also graphviz 2.20.2. I have been trying to install Rgraphviz either from R running "biocLite("Rgraphviz")" and from the shell

You are right and the problem is solved. Re: about the possible errors in Rgraphviz Package
Hi Martin,
It is really a 'PATH' problem. After adding C:\Program
Files\Graphviz2.20\bin to the 'PATH' environment variable, the
Rgraphviz package can be loaded without any error messages.
Sorry that I ONLY set my 'PATH' environment variable correctly
for R but not for Graphviz.
Thank you and Duncan so much for your great help.

package Rgraphviz or similar
Hello R users
I am looking for a package to visualize "relatively
planar" directed graphs, with say 100 nodes and
specified using an adjacency list.
'Rgraphviz', currently listed on the R-FAQ, seemed
suitable (FAQ version 2.9.2009-06-05)
But when I looked for the package, I found it had been
recently "removed" and was instead directed to archive

How to build a package which loads Rgraphviz (if installed)...
Dear List,
I use Rgraphviz for display of graphs in some packages. Since Rgraphviz is no longer on CRAN it needs to be installed from Bioconductor and that is fine, but I have trouble figureing out the following: I create a plot method which - if Rgraphviz is installed - uses Rgraphviz for displaying and otherwise does nothing. This is implemented as:
