similar to: 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

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 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

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

Hello, I want to have a title that will look something like: "Results for \theta=2.1", given that I have a variable theta=2.1, and \theta should show on the screen like the greek letter. I've tried a lot of things: theta <- 2.1 plot(1:10, main=expression(paste("Results for", theta, "=", eval(theta)))) or using bquote plot(1:10, main=paste("Results for

Hello, I have the following example. testpdf <- function(x,y){ pdf() #plot(x,y) xyplot(x~y) dev.off() } source("testpdf.R") x=1:1000 testpdf(x,x) with "xyplot", the output is a file that can not be read because it has no pages. With "plot" it works fine. If I do it manually (from the GUI menu), it works even for "xyplot". How can I save

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, I've just produced my first lattice plot - the graphic is very impressive, but I only partly understand how it works. I crimped from examples in MASS and the help pages to get most of what I want done. Howver, I find both MASS and the help pages are a little too terse for my needs as a beginner. Can anyone suggest web or print resources for lattice graphics that provide a more thorough
