Hello I am trying to draw a basic black and white map of two European countries. After searching some key words in google and reading many pages I arrived to the conclusion that persp() could be used to draw that map. I have prepared three small example files, which are supposed to be the files required for running that function. xvector is a vector with the longitudes yvector is a vector with

Hi all, I'm handling massive data.frames and matrices in R (30000 x 400). In the 1st column, say, I have 0s and 1s indicating rows that matter; other columns have probability values. One simple task I would like to do would be to get the column mean values for signaled rows (the ones with 1) As a very fresh "programmer" I have build a simple function in R which should not be very

I am running R 2.7.0 on a Suse 9.1 linux cluster with a job scheduler dispatching jobs and openmpi-1.0.1. I have tried running one of the examples at http://ace.acadiau.ca/math/ACMMaC/Rmpi/examples.html in Rmpi and they seem to be working, except mpi.close.Rslaves() hangs. The slaves are closed, but the master doesn't finish its script. Below is the example script and the call to R. The job is

Hi, I'm testing the efficiency of the Rmpi package regarding parallelization using a cluster. I've found and tried the task pull programming method, but even if it is described as the best method, it seems to cause deadlock, anyone could help me in using this method? here is the code I've found and tried: # Initialize MPI library("Rmpi") # Notice we just say "give us

> Or is this a bad idea? I don't like the proposal. I have seen code like the following (in fact, I have written such code, where I had forgotten a function was not vectorized) where the error would have been discovered much later if outer() didn't catch it. > outer(1:3, 11:13, sum) Error in outer(1:3, 11:13, sum) : dims [product 9] do not match the length of object [1]

Dear all, I have used the Rmpi package many times before however this time I've installed it as I always do with openMPI tar.gz file direct from the website. I'm installing on my ubuntu 8.10. Linux 2.6.27-11-generic #1 SMP Thu Jan 29 19:28:32 UTC 2009 x86_64 GNU/Linux All i get is: > library(Rmpi) Segmentation fault :~$ Which dumps me back into the shell, and doens't give me much

Hi, So far I used Sweave to create pdf reports. I used xtable to create some tables in the report. But now I would like to use the same snw file to generate an HTML version. The xtable output breaks the RweaveHTML driver. library(R2HTML) Sweave('analyseLFQ.Snw', driver = RweaveHTML) Error in match.arg(options$results, c("Robj", "html", "hide")) :

GEM object functions deprecate several similar callback interfaces in struct drm_driver. This patch replaces the per-driver callbacks with per-instance callbacks in radeon. v2: * move object-function instance to radeon_gem.c (Christian) * set callbacks in radeon_gem_object_create() (Christian) Signed-off-by: Thomas Zimmermann <tzimmermann at suse.de> ---

Hello, I have got a question. I've got a matrix (mail end) with the colnames x, y, z. In this matrix are different measurements. x and y are risign coordinates. My question. Always, if the "x" AND "y" coordinates are the same, I want to get the mean of their z values. e.q. " x" AND "y" in line1 and line8 are identical: 29 4.5 --> mean of

I have a package that can use rmpi, but works fine without it. None of the automatic test code invokes rmpi functionality. (One test file illustrates how to use it, but has quit() as its first command.) What's the best way to handle this? In particular, what is the appropriate form for upload to CRAN? When I omitted rmpi from the DESCRITPION file R CMD check gave <quote> * checking

Dear R Users, Given two vectors, say a = seq(2) and b = seq(3), I want to make an 2*3 array, where (i,j) element is list(a=a[i], b=b[j]). I tried the outer() function but it generates an error message that I don't understand, see below. What do I do wrong? The expan.grid function is not good enough since I need a solution that works when a and b are not atomic, say a=list(list(x=1,

Hello, I am attempting to install Bioconductor on 64 bit R. The installation of some bioconductor packages fails with the errors below. I would be very grateful for any help on how to resolve the issue. Best regards, Octavio Espinosa --------------------- Most of the bioconductor packages won't install, for examples 'Biobase' errors with: ** building package indices ...

Rework fbdev probing to support fbdev_probe in struct drm_driver and remove the old fb_probe callback. Provide an initializer macro for struct drm_driver that sets the callback according to the kernel configuration. Call drm_client_setup() to run the kernel's default client setup for DRM. Set fbdev_probe in struct drm_driver, so that the client setup can start the common fbdev client. The
