[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

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: if (!("package:Rgraphviz" %in%

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 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. set.seed(31)
