I have been wanting to drop all the rows if there values are `NA' or have specific values like 1 or 2 or 3. mdat <- matrix(1:21, nrow = 7, ncol=3, byrow=TRUE, dimnames = list(c("row1",

Dear all, I have a large matrix with about 2500 variables, and 100 rows. I would like to calculate the means of the every 10 variables starting from 1:2500 and saving the results as a vector or matrix. How can I do that? Alternatively, How can I create 250 subset matrices in the order of variables 1:2500 in groups of 10 from the single matrix which had initially 2500 variables ? I guess I have

Hi Everyone, Those of you who have a simple home-based Asterisk box might be interested in a "simple" Win32 (Win2K or WinXP) interface to the AMI manager. The quick-start versions merely require unzipping with NO Installation - hence, NO Uninstall (i.e., no registry writes at any time by the install nor by the program). (Unfortunately) the INSTALL version does write to the

Hello all, is it possible to use the native Linux libraries instead of their Windows builds? This can be a newbie question. :) I have a database program based on PostgreSQL and I think that coyping the Windows libraries for the application to run is a bit luxury when the same but native libraries with the same functions already exist for Linux and they are already installed on my system. I

Hi, I'm a Delphi (Windows) developer and I was trying to use Wine to execute my applications on Linux (actually using a Kubuntu 8.10) Most thing works great, but some don't.

This is probably a Suse specific problem and not a bug in R, but I'm reporting it in case it's useful for someone to know about.... Trying to compile R1.9.0 from source on a standard Suse 9.1 install (athlon in a shuttle sn41g2). configure seems fine but the Suse X11R6 Xlib.h might be toxic. In case it helps, here's the sad end to the make output. I can post the Xlib.h if that
