similar to: Replacing all NA values in a matrix

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 I have recently installed and implemented Xvfb (X virtual frame buffer) so that I can create jpegs using R over CGI (SUSE Linux 8.1 and Apache 1.3). I have noticed that in order to do this, a file (Rplots.ps) is created in my cgi-bin directory everytime a cgi script is run. This could cause problems though as I have a multi-user system where it is possible that two different users will run

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

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 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

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 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

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, Our desktop clients are running CentOS 7 with the Xfce desktop from EPEL. The CR repository is enabled. A few days ago I launched an update, which brought in close to 1 GB of packages. I had some weird problems on two clients. One is an old Dell Optiplex 330 with a legacy video card.

I have a server running Ubuntu natty (libvirt 0.8.8) with separate ethernet interfaces. I have created an unnumbered bridge for each interface, these are connected to an already established network infrastructure, with preexisting DHCP and DNS services. I would like to handle *establishment* of these bridges outside libvirt (via /etc/network/interfaces), but still have them defined as networks

Hi, I'm not in the list and I just would like to comment it to the comunity. So, if someone want to contact me, make CC to me in the reply. The wiki page [1] talk about networking, and show two typical configurations: "virtual network" and "shared physical device". The shared physical device has an error or something that could make confused, I think. What I want to
