Hi I have seen a few posts to this list regarding problems accessing the x11() device over cgi - namely, when trying to create a graphic using the jpeg() function, everything is fine from the command line but it won't work over cgi, producing the error: "Unable to open connection to X11 display" Has anyone actually solved this particular problem satisfactorily? Please reply

OK, dumb question, and it is probably in the docs somewhere, but after 12 months working with R and quite a while looking at the docs, I still don't know (or have forgotten) how to replace all NA values in a matrix at once with some other value. I can do it column by column using is.na(), but I can't figure out how to do it for the whole matrix. My apologies, I am ashamed ;-) Michael

Hi First a simple question to do with plot(). How do I change the x-axis labels on a plot? For example, I am plotting each row of a matrix, and I want each row to be a line on my graph. Simple really. Eg: plot(sg[1,], type="l") When I do this, the x-axis is labelled 1:38, as I have 38 columns in my matrix. When I do: plot(sg[1,order(sg[1,])], type="l") Ideally I would

Hi Running R v2.0 on SuSe linux 8.2. I'm trying to build a package (which built perfectly on Windows...) on Linux, and I ran: R CMD check mypackage I got: * checking mypackage-maual.tex ...

Hi I'm seeing some "odd" behaviour with cbind(). My code is: > cat <- read.table("cogs_category.txt", sep="\t", header=TRUE, quote=NULL, colClasses="character") > colnames(cat) [1] "Code" "Description" > is.factor(cat$Code) [1] FALSE > is.factor(cat$Description) [1] FALSE > is.factor(rainbow(nrow(cat))) [1]

Hi You may remember a while ago I was having problems with creating jpegs using R over CGI. I solved this on my LAPTOP (*grins*) by - executing "xhost +localhost" from the command line - putting "SetEnv DISPLAY=:0.0" in my httpd.conf (apache) And all worked well. Now I'm trying to move the whole system onto my shiny new server - and encountering yet more problems

Hi When I use plot(hclust(dist..)...)...) etc to create a dendrogram of a hierarchial cluster analysis, I end up with a vertical tree. What do I need to do to get a horizontal tree? Also, my users are used to seeing trees who's leaves all "end" at the same place (eg. Like in minitab). Is this possible in R? Thanks Mick Michael Watson Head of Informatics Institute for Animal

Hi I am running an R script that creates 100s of graphs, and I need to use the greek CAPITAL letter delta in the mtext() function. I got as far as expression(delta) but this gives me the lowercase version. Can anyone help?

Following on from my previous mail! plot(1:10,1:10) mtext("title", side=3, adj=0, font=3, cex=1.5) This works as expected and puts the font in italics. tag <- "A)" suffix <- "genea::" plot(1:10,1:10) mtext(bquote(.(tag) ~ Delta * .(suffix)), side=3, adj=0, font=3, cex=1.5) Here, the font isn't in italics, it's normal. I presume this is some

Replacing the NA?s with eg. 1 : > a 1 2 3 4 1 20 50 10 80 2 NA 19 NA 49 3 NA 32 NA 61 4 45 101 44 190 a[try(is.na(a)) == TRUE] <- 1 > a 1 2 3 4 1 20 50 10 80 2 1 19 1 49 3 1 32 1 61 4 45 101 44 190 I this can help you, Matthias > -----Urspr?ngliche Nachricht----- > Von: r-help-bounces at stat.math.ethz.ch > [mailto:r-help-bounces at

Hi I am applying the wilcoxon paired signed rank test to many sub-groups of a data frame using by() and wilcox.test, and sometimes the test uses continuity correction and sometimes it doesn't. What I want to know is: 1) what is continuity correction? The docs say: correct: a logical indicating whether to apply continuity correction in the normal approximation for the p-value.

Hi there, Does anybody have experience in running jpeg device using xvfb-run on linux? I've been having sporadic problem with: /usr/X11/bin/xvfb-run /usr/bin/R --no-save < Rinput.txt, with error saying: error in X11 connection. Especially when I run it from a perl script. Is there a better way of doing this? or how can I fix the problem. Thanks in advance! David [[alternative HTML

Yesterday I cloned one of my VMs and, somewhat implausibly, it took virt-clone something like 8-9 hours to clone the 8Gb disk image... Copying it from the command line took a mere 6.5 minutes. I assume this is a bug, and it's not expected to take this long ;-) This was using virt-clone from python-virtinst-0.500.2-1.fc12.noarch in the virt-preview repository. Tom -- Tom Hughes (tom at

Hi, I use R in remote access on a Debian server. I need X11() to create graphical things so I use xvfb-run (Virtual X server environnement) R to allowing X11() capabilities to R. An other technique is to connect in shh -X to execute my R script. With the connection ssh -X, my R script is well executed. BUT when I use Xvfb, some graphics are created but an error occured and stop the script.

I'm trying to render a acad dwg picture to swf so I can display in a web page.. I have Xvfb set up since this is a webserver and I needed a virtual space.. When I run my app I get this error.. err:module:attach_process_dlls "odbc32.dll" failed to initialize, aborting err:module:LdrInitializeThunk Main exe initialization for L"C:\\Program

First, I realize this might not be the right group. Please feel free to redirect me :-) I recently upgraded from CentOS 5.6 to 6.0. Since the upgrade, Xvfb will, on occasion, "just stop" (ie the process disappears from the system, as opposed to still being there but not working). I can't find any tracks anywhere that it might have left behind that might be clues as to why it
