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. Adrian Dragulescu

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

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

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)

Hi all, I have a question regarding the Rgraphviz package. Does anybody know how to add x-Axis and y-Axis with scale to the plot generated by renderGraph( ). Or, is there any althernative way to do so by using plot( ) instead ? Thanks, -- Jiayi Hou Ph.D Candidate Department of Biostatistics School of Medicine Virginia Commonwealth University Tel:(804)-828-2879(office) (804)-274-8757(cell)

It is a trivial matter to adjust the linewidth of the axes and plot line in a 2D plot: x <- 1:10; y <- 1:10; par(lwd=2); # axis (and others) linewidth plot(x,y,"l",lwd=6); # plot linewidth Is there anything comparable to this for persp or wireframe? I've tried a number of ways, and the framebox/axes seem to be linked to the linewidth used in generating the

Hi, I am installing Rgraphviz at Linux Fedora Core 2 with 32 bit AMD athlon with 512 RAM. I have installed graphviz version: graphviz-1.16-1.src.rpm installed already on system.

Dear experts I installed Rgraphviz with the following command: source("http://www.bioconductor.org/biocLite.R") biocLite("Rgraphviz") But had a problem when I tried to load it. This says that libcdt-4.dll is missing in your computer and the following message in R window: > library("Rgraphviz") Loading required package: graph Loading required package:

Hello I desperately need help with installing the Rgraphviz package under windows 7. Please forget my ignorance of basic topics, I’m a psychiatrist trying to use text mining to analyse psychiatric reports for criminal courts, statistics and machine learning are within my reach but R environnement subtleties not really...

Rgraphviz Install works fine (http://www.bioconductor.org/packages/release/bioc/html/Rgraphviz.html) Latest version of graphviz is installed as well however I get following error when loading Rgraphviz (on Mac 10.6.2) Error in dyn.load(file, DLLpath = DLLpath, ...) : unable to load shared library '/Users/jb/Library/R/2.9/library/Rgraphviz/libs/i386/Rgraphviz.so':

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%

Dear r-helpers, Can anyone suggest a remedy to the following failure of Rgraphviz to load? > library(Rgraphviz) Loading required package: graph Loading required package: Ruuid Error in dyn.load(x, as.logical(local), as.logical(now)) : unable to load shared library '/Library/Frameworks/R.framework/ Resources/library/Rgraphviz/libs/ppc/Rgraphviz.so':

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

Hola a tod@s, ayer mismo gracias a CarlosJ. Gil Bellosta me he enterado de la existencia de la lista R en España. Excelente idea!!

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

I have a figure on screen with a legend. I want to copy this image to EPS, and use: dev.copy2eps(file="file1.eps", width=5, height=5) The legend that looks OK on screen doesn't look OK in the PostScript image: the text extends out of the box. I try adding a fontsize command: dev.copy2eps(file="file1.eps", width=5, height=5, pointsize=5) This options seems to

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

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).
