similar to: Rgraphviz: Setting the edge width

Using Rgraphviz, I draw the undirected graph with vertices A,B,C and D and edges A:B, B:C, C:D, D:A, A:C. I want the vertices A and B to be red and C and D to be blue. The problem is the following: I want the edges A:B and B:C to be green and the edges C:D and C:A to be yellow, while the edge A:C can have the default colour black. I assume that I have to specify this using the edgeAttrs-argument

I have developed a problem with the postscript output of plot on Windows. My code still works properly with R 2.3 but, with R 2.4, the white text on red background does not show up. It does, however, show up when output is sent to the screen. Below is my code and sessionInfo.

Hi, I'm trying to create a connectivity diagram using RgraphViz library. I want to increase the edge's label fontsize, but the size did not change. Did I do something wrong ? M <- matrix(nrow=5,ncol=5,byrow=TRUE,data=mytable) colnames(M) <- levels(pf$agent) A <- new("graphAM", M, "directed", values = list(weight=M)) eAttrs <- list() ew <-

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 ->

Hi All, After a lengthy battle just to get the package installed, I am not able to actually use Rgraphviz to generate any plots. I tried just using the sample code in the documentation (http://www2.warwick.ac.uk/fac/sci/moac/people/students/peter_cock/r/rgraphviz/) and I get the following: *> > library(Rgraphviz) > test.matrix<-matrix(rep(c(0,1,0,0), 9), ncol=6, nrow=6) >

Can you please show code example, how to draw graph with some nodes and edges, but with weights. I only found here http://www.bioconductor.org/packages/release/bioc/vignettes/Rgraphviz/inst/doc/Rgraphviz.pdf- Using edge weights for labels, but... Here an example: > library("graph"); library(Rgraphviz) > myNodes = c("s", "p", "q", "r") >

Here are my patches to add extra shapes to the annotate plugin. I have also added dbus support and made a few things configurable. The new tools available are Line, Rectangle and Circle, the original is called Brush. There is no selection line at the moment because I do not understand OpenGL yet. Hopefully these patches can be added and something added later. There is an extra action called

Hi guys at mapstraction, I made a change in the Polyline.toMicrosoft() function, in order to have all the power that a VEShape has, for instance fill color. Below is the new code, if you want to use it, change it, or whatever. Cheers, Beta /** * toMicrosoft returns a Microsoft polyline * @returns a VEShape */ Polyline.prototype.toMicrosoft = function() { var mpolyline; var mpoints

The current way of handling refcounting in the DP MST helpers is really confusing and probably just plain wrong because it's been hacked up many times over the years without anyone actually going over the code and seeing if things could be simplified. To the best of my understanding, the current scheme works like this: drm_dp_mst_port and drm_dp_mst_branch both have a single refcount. When

Hi Gabor, I just used your R code below and the code worked properly without any error messages. Attached is the output graph, which may be the one you expected. library("Rgraphviz") set.seed(123) V <- letters[1:10] M <- 1:4 g1 <- randomGraph(V, M, 0.2) g1 plot(g1) Thanks.

Daniel, muchas gracias por contestar y tan rápido. Pues puede ser la solución, he hecho el cambio y sigue sin pintarme los puntos -> data_ <- toJSONArray(data_, json = F) map$geoJson( # leafletR::toGeoJSON(data_, # # lat.lon = c('Lat', 'Long'), # dest=output_geofile), data_, onEachFeature =

Hello, My question is regarding the interpretation of --stats output and whether I have a performance issue or not. Can the client/server architecture (rsync client on one machine, rsync server on another machine) be far slowlier than a local rsync session ? This is the ouput of an rsync session: date rsync -v --recursive --links --perms --times --group --owner --xattrs --acls --delete

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... I have read existing posts on rgraphviz installation problems that I have

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%
