[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)))

Dear experts
I installed Rgraphviz with the following command:

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:

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
copies

linewidth in Rgraphviz
I'm an Rgraphviz newbie trying to figure out how to do some things/whether
they are possible.
Apparently graphviz does allow you to modify line widths of edges: see
https://mailman.research.att.com/pipermail/graphviz-interest/2001q2/000051.html
(although it looks a little obscure even in graphviz). [As discussed in the
thread
above, the "weight" parameter in Rgraphviz sets the

Rgraphviz and R 2.9 in ubuntu jaunty
Dear people,
I'm new here, so this is my first try. I have ubuntu 9.04 installed with R 2.8 (which surprises me because I realized that the last version R 2.9 is available but in the Synaptic Package Manager 2.8 appears as the last one). I have also graphviz 2.20.2. I have been trying to install Rgraphviz either from R running "biocLite("Rgraphviz")" and from the shell

Installing Rgraphviz package on a windows vista pc
Hi,
I want to install Rgraphviz on a windows vista pc. The only source file that I found in the bioconductor homepage is a tar file. I can't install from this using the packages command in the R menu. I would like to get some tips on how I can do the installation.
Can I just place the extracted Rgraph folder (from the source tar file) in the library folder of R2.6.1 along with the other

Rgraphviz install
Hi
I've tried several times and followed what others suggest in installing Rgraphviz (https://stat.ethz.ch/pipermail/bioconductor/2008-June/022838.html)
But I could not load library(Rgraphviz).
There's a message that 'This application has failed to start because libcdt-4.dll was not found'
Could anyone suggest me how to make it work?

Rgraphviz ignoring outputorder attribute
Hi - since Rgraphviz was officially moved over to Bioconductor, this might
be a misguided post, but it's worth a shot:
I'm plotting a graph using Rgraphviz and in an attempt to force the edges to
be behind the nodes (on a fairly complex graph), I set the "outputorder"
graph attribute to "edgesfirst" (as is described in the graphviz docs here

Memory leak using Rgraphviz
I'm running an Ubuntu 10.04 system and installed R 2.10.1 through the package manger. I then installed Rgraphviz 1.24 and graph 1.26 through R.
I'm trying to understand why a complex function my team wrote causes R's memory footprint viewed through top to increase every time it's run. I traced the increase in memory usage to layoutGraph() and wrote the following short function

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.
