Hello, I'm applying an arithmetical function the color (R,G,B) of each pixel of a figure and it's very slow. This is common? Other thing, are there some library to make modification in figures, eg, to alter size? If not, somebody knows some software that makes this, or either, to resize figures automatically, therefore I go to need to apply to a bank. Tks, Francisco.

Hi R users: I got the following message when I use the pixmap library on R 1.7.0 over w2K platform (on R 1.6.2 it runs right). pixmapGrey(matrix(c(0,1),128,128)) Error in .class1(object) : Object "from" not found I download the library .zip file from: http://cran.r-project.org/bin/windows/contrib/1.7/pixmap_0.3-2.zip Other question: When I try to "Install package(s) from

Reposting from virt-tools mailing list: Hi! I'm facing a problem that could be triggered by some lacking of support from libvirt on Open vSwitch (or could be my mistake). I have interests in researching on virtual networks and SDN. To keep things simple, I've decided to use libvirt/virt-tools to manage VM's since my focus is on the network, instead of using a full feature system

I have just upgraded from Red Hat Linux 5.2 to version 6.0 (with GNOME) on an intel box. I have also upgraded to the latest R version (0.64.1-2 rpm) and have also installed the corresponding GNOME rpm. However, I am not able to start R: [cribari at edgeworth install]$ R /usr/lib/R/bin/R.binary: error in loading shared libraries: /usr/lib/R/bin/R.binary: undefined symbol: __setfpucw [cribari at

I am running R 1.2.1 under Mandrake Linux 7.2 (installed from RPM) and I installed a few packages using install.packages() . Now, I am trying to upgrade these packages using update.packages() but I believe I am running into some kind of error. See below. Any tips will be greatly welcome. Thanks in advance. Francisco PS: update.packages() only tries to update wle from version 0.3 to 0.4, gives

Hi! After unziping the CRAN file e1071.zip on my Win95 library directory, I start R and type >library(e1071) After that, help commands of the e1071 functions work (i.e., help(read.pnm), BUT some functions themselves are not available: > read.pnm Error: Object "read.pnm" not found I've looked at the file library/R/e1071 with an ascii editor and it seems like the functions

OK, I am forwarding this to the r-help. In the original message I simply hit reply and I thought I send to ALL r-help list. (apparent not) also I recieved another piece of mail.....about the RNG in Splus 4.0 or later indicating it was modified and getting worse. I only have Splus 3.4 for HP. So I cannot try it. This makes the idea of using the pre-generated RN on CDROM more appealing.. Mai

You can have multiple vethX interfaces on recent builds -- see netback/loopback.c. I think the current default is a rather miserly 1 (and should be increased), but can be set on the command line.

Hi, I am trying to use "read.pnm" from the package "pixmap" to read more than 10 thousand image files in "mydir". > file.list <- dir( "mydir", full=T) > for( i in 1:length(file.list) ) { print(i) x <- read.pnm(file.list[i]) } In the beginning it was fine. But after reading 1020 images or so, the read.pnm function seems to crash on

Hi, I'm having trouble writing .pnm images which I think is due to a problem with my colour space. The pixmap object seems to be looking for 72 of 8 colours (one per cell?) which doesn't seem healthy... > library(pixmap) > x <- pixmapIndexed(rep(1:8, 9), nrow=6, col=rainbow(8)) > x Pixmap image Type : pixmapIndexed Size : 6x12 Resolution : 1x1

Can a single random number be generated in R? I have an exercise that wants to simulate coin tosses, and I cannot seem to find a good example of the use of random number generation in R. Any help? Joshua Gramlich Chicago, IL

In R-beta (Masked Marvel), when I do the example from the read.pnm help file, this is what happens: x <- read.pnm(system.file("pictures/logo.pgm",package="pixmap")[1]) Warning message: In rep(cellres, length=2): x is NULL so the result will be NULL In R-2.15.3, it's all right.
