I just installed Rmpi on my 64-bit Ubuntu Hardy Heron OS and using the following without errors: "R CMD INSTALL Rmpi_0.5-5.tar.gz --configure-args=--with-mpi=/usr/lib64/openmpi" Immediately at library(Rmpi) I get the segfault displayed in my complete output below. My first thought is that perhaps I used the wrong library for openmpi, but with my 64 bit install it seemed like a logical

Subject pretty much says it all. I am running 64-bit Ubuntu 8.04, i.e. Hardy Heron, have openmpi installed, and get the following error message with attempted install of Rmpi. sessionInfo() follows.

Recently I posted to this list with a question about using the Intel 10.1 compilers in building R and one response was basically, "why in the heck would you want to do that?" The answer is that my sysadmin believes that there will be a performance boost with the Intel vs. Gnu compilers on our Linux cluster, of which I am one of many users.

I'm trying to use the rgl package on R-2.7.1 running on top of Ubuntu Hardy amd64. using open3d() and plot3d() I get a plot, but it is not interactive. Furthermore, changes to par3d("FOV"=my.new.value) do nothing. I suspect something is wrong with the rendering engine or interface to it. I do have an Nvidia driver installed and compiz works correctly on the desktop. I've

I would like to create a 3d scatterplot that is interactive in the sense that I can spin it on its axes to better visualize some PCA results I have. What are the options in R? I've looked at RGL and perhaps it will suffice but it wasn't apparent from the documentation I found. Any demo scripts available for a package that will work? Mark -- Mark W.

I am running 64-bit Ubuntu 8.04 and when I invoke rggobi the interactive graph displays but R crashes. See my sessionInfo() and a short example below. Ggobi and rggobi installed without complaints. Mark > sessionInfo() R version 2.7.0 Patched (2008-05-04 r45620) x86_64-unknown-linux-gnu locale:

I can compile RSPython without difficulty, been when I try to load it, I get the error messages below. Also below are some cryptic warnings I get on R boot (in case these are pertinent) and my sessionInfo(). Any help is appreciated.

I'm having trouble achieving the results I want using a regular expression. I want to eliminate all characters that fall within square brackets as well as the brackets themselves, returning an "". I'm not sure if it's R's use of double slash escapes or something else that is tripping me up. If I only use one slash I get 1: '\[' is an unrecognized escape in a

I'm making some plots on the same page and would like to include an overall title instead of individual main titles as they are similar and their x and y axis labels are sufficient to distinguish them. Is there a way to assign an overall "main" to this page of plots? Mark -- Mark W. Kimpel MD ** Neuroinformatics ** Dept. of Psychiatry Indiana University School of Medicine 15032

I'm having trouble with a Bioconductor package, an variable expected in an environment does not seem to be there. As part of my investigation of the problem (most likely on my end) I'd like to list the variables contained in an environment. If you have an environment loaded, lets call it "pkgEnv', how does one find what it does contain? Mark

I have a very long list of strings. Each string actually contains multiple values separated by a semi-colon. I need to turn each string into a vector of the values delimited by the semi-colons. I know I can do this very laboriously by using loops, nchar, and substr, but it is terribly slow. Is there a basic R function that handles this situation? If not, is there perhaps a faster way to do it than

I am running a very long loop and would like to save intermediate results in case of a system or program crash. Here is the skeleton of what my code would be: for (i in 1:zillion) { results[[i]]<-do.something.function() if (logical.test(i)) {save(results, "results.tmp")} } logical.test would test to see if i/1000 has no remainder. What R function would test that?

I have a very long list that I'd like to subset based on a logical value within each element. Example below. I'd like to get just those list elements for further study whose $sig.cor slot is TRUE. In this example, I'd only want element [[2]]. Should be simple, I know. How can I do this? Thanks, Mark > gene.pair.tf.lst [[1]] [[1]]$gene.pair [1] "Lgals1:Pxmp2"

I am getting some unexpected results from some functions of igraph and it is possible that I am misinterpreting the vertex numbers. Eg., the max betweenness measure seems to be from a vertex that is not connected to a single other vertex.

I have recently upgraded to Ubuntu Gutsy and, for the first time, am using a 64-bit installation. After failing miserably to install R from source, not a problem for me in the past with a 32-bit install, I went the route of using the Debian Etch build. This went smoothly, but I am unable to update my numerous R and BioConductor packages, getting non-zero exit status errors on each package. Is

I have fit a model to ~20k different genes and would now like to extract the p-val for one of the effects, again for each individual gene. My model code is: mod <- lm(myResponseMatrix~ Time) Were I to do this with a response vector rather than matrix, the following would work: anovaResult<- anova(mod) With a more complex lm object, such as that generated above, it seems anova is trying to

I just downloaded R-devel and when loaded it immediately segfaults. I'm not sure how much or what sort of diagnostic info and can provide, but below is my build script, my console output, and the output of uname -r. I am currently dependent on the development version of a package, so I'd like to get R-devel up and running if possible. I am sure there is more info I can provide, but before

Just installed the latest R-patched and get the error seen at the end of the output below. Don't know what to make of this but thought I should report it. In general, when installing the latest version of R, should one use R-latest or R-patched? R-latest is stable, but one would assume that R-patched includes the latest bug fixes.
