controlling the edge linewidth in Rgraphviz
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

greek letters, text, and values in labels
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

ROracle error in Windows. Memory could not be read.
I've seen from earlier posts that other people had problems installing ROracle under Windows. I run R-2.3.1.

merge performace degradation in 2.9.1
I have noticed a significant performance degradation using merge in 2.9.1 relative to 2.8.1. Here is what I observed: N <- 100000 X <- data.frame(group=rep(12:1, each=N), mon=rep(rev(month.abb), each=N)) X$mon <- as.character(X$mon) Y <- data.frame(mon=month.abb, letter=letters[1:12]) Y$mon <- as.character(Y$mon) Z <- cbind(Y, group=1:12) system.time(Out

[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

Does pdf() not work on Trellis graphics?
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

learning lattice graphics
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

problem packaging S4 class that contains a slot of jobjRef class

Speex Support for Ices?
wget ices*bz2 fgrep ./* -e "speex" ? fgrep ./* -e "ogg" ? Can't remember the exact lib name(s), but speex is very similar to vorbis/ogg lib implementations. So whomever wrote ices, would probably have a pretty easy time incorporating it. Well, before I do anything, I still need to get my program outputting usable metadata.

Ezstream & oggfwd apparently do not stream from Alsa. I've seen some acrecord command line options, but it would also be nice to update metadata often too. Ices seems best. I've

domU doesn't see all memory
Hi, I'm running CentOS 6.2 x86_64 as xen guest on a CentOS 5.7 dom0. The host is running 2.6.18-274.7.1.el5xen, the guest 2.6.32-220.2.1.el6.x86_64. Memory for domU is set to 1024 MB and "xm list" shows these 1024 MB. But "free -m" on the guest system shows only 652 MB. When I set up a CentOS 5.x guest with 1024 MB "free -m" shoes 1024 MB.

How to use alpha transparency channel for colors?
The release notes for R 2.0.0 states: It is now possible to specify colours with a full alpha transparency channel via the new 'alpha' argument to the rgb() and hsv() functions, or as a string of the form "#RRGGBBAA". NOTE: most devices draw nothing if a colour is not opaque, but PDF and Quartz devices will render semitransparent colours. A new argument

Instance-backed CentOS AWS AMIs?

Still though, also the instance-backed AMIs are listed as published and available on your wiki: http://wiki.centos.org/Cloud/AWS I've seen that the same question was asked already before but I'm not sure the answer given actually covered the whole question:

Xen4CentOS6 project longevity
We've been using CentOS 5 with Xen on our machines for a while now and have really grown to appreciate it. The lack of Xen for Centos 6 is the reason we haven't upgraded yet, but with Xen4CentOS6 we have all the tools we need. The concern some of are having is that when CentOS7 comes out, which will be probably less than a year, is that Xen support for CentOS6 will evaporate. I know this

Hey
Just want to let you guys know that, although it may have been around for a bit, bringing Xen back to CentOS is awesome and I really appreciate it. I was very disappointed when RedHat dropped support as Xen is awesome. Thanks for the effort!
