Hi Stefan, Thank you very much for pointing me to the wordspace package. It does the job a bit faster than my C code but is 100 times more convenient. By the way, since the tcrossprod function in the Matrix package is so fast, the Euclidean distance can be computed very fast: euc_dist <- function(m) {mtm <- Matrix::tcrossprod(m); sq <- rowSums(m*m);? sqrt(outer(sq,sq,"+") -

Hi, first of, my apologies for the possibly off-topic message regarding a problem when installing the XML package (I meant to post at omegahat- help, but I get 404 at http://www.omegahat.org/mailman/listinfo) When installing the XML package using: install.packages("XML") everything seems to go fine... but then I try to load the package and I get: > library(XML) Error in

I'm bringing this issue to r-devel as my idea of sending it to r-help appears to be wrong. The following is reproducible in R-patched and R-devel (also in older versions). An outlier is inserted in group E and the last plot by plot.lm suggests that the point belongs to D. It appears to me that: * (facval, rsp) and * x$xlevels[[1L]][order(sapply(split(yh,mf[,1]), mean))] are sorted

Hi, I'm observing the following warning with R-2.10.0 on a machine I have remote access to. Like what happened to Roger ( http://www.mail-archive.com/r-devel at r-project.org/msg08669.html ), two extra instances of X11 are open after dev.off(). Although I'm reporting this on R-2.10.0, it's reproducible on R-devel r50541. Any thoughts about this? Thanks a lot for any info, b >

Hi everyone, it's been a while I've been trying to save a plot created via lattice:::xyplot if I have a file tst.R with the following code: y <- rnorm(100) x <- rnorm(100) z <- sample(letters[1:4], 100, rep=T) library(lattice) bitmap("tst.png") xyplot(y~x|z) dev.off() and I source it, I get the tst.png file, which is a blank page. If I copy and paste instead, I

Hi, Until now, I thought that the results of glm() and bigglm() would coincide. Probably a naive assumption? Anyways, I've been using bigglm() on some datasets I have available. One of the sets has >15M observations. I have 3 continuous predictors (A, B, C) and a binary outcome (Y). And tried the following: m1 <- bigglm(Y~A+B+C, family=binomial(), data=dataset1, chunksize=10e6)

Hi, I've using package DEXSeq that implements functions with nCores for speed-up. The functions work fine, but I found out that the children processes were not terminated, they still hold memory, and new command will start up new children processes. So if I don't manually kill those orphan processes, they will cause problem. I was qlogin to SGE cluster node to run R. From our

Hi, I am trying to install GenomeGraphs package from bioconductor, but failed by a non-zero exit error. From the error message, it seems that there is a shared library problem.

hey people I'm new to the list and would like to say thanks to everyone that has worked on syslinux/isolinux. It's one of those tools that everyone uses at some stage but no-one ever really takes much notice of it - mainly because *it just works*. So congrats ... Now onto my question - I am customizing Fedora Core and I want to change the isolinux boot.msg screen to display some

Hi, I tried Rsync 3.0.0pre8 on my mac running os X 10.5. I was very pleased about the --iconv feature, as i have to sync some LINUX-machines and I had really trouble with some filenames. But I found one strange thing in connection with the mac. First of all, the translation between the LINUX ISO-8859-15 and the mac ut-8 works (nearly) perfect. As I live in Germany, we have often filenames

Hi all, This has been very frustrating for me trying to get this acts_as_ferret working well on a Fedora box. On my mac it works great, no problems with locale, but when I put the code live on my Fedora server, it complains about the locale setting (Error occured at <analysis.c>:498 Error: exception 2 not handled: Error decoding input string. Check that you have the locale set

Hello: I was wondering, has anyone has encountered an R package that performs random projection/random mapping? RP is a procedure that is akin to Principal Components Analysis in that it accomplishes dimensionality reduction, but is far more computationally efficient. I have been searching for some time, but haven't seen anything on CRAN-r yet. David Monaghan Sociology Ph.D. Candidate,

Dear R developers, I am visualising high dimensional genomic data and for this purpose I need to compute pairwise distances between many points in a high-dimensional space (say I have a matrix of 5,000 rows and 20,000 columns, so the result is a 5,000x5,000 matrix or it's upper diagonal).Computing such thing in R takes many hours (I am doing this on a Linux server with more than 100 GB of RAM,

I have tried Samba 3.0.2a and 3.0.4. We use Active directory. The server is running on RHEL3. When I connect to the server on a share that is acutally an ext3 or NFS file system, I have no known problems. We use ClearCase on Linux and I am trying to access my workspace (view) as I have done many times before on Solaris, but now we are running on Linux and with a newer version of ClearCase
