Hello, I have a question about how R can run automatically. Here is the story: A file called "data.csv" will be generated every couple of minutes in a folder (overwrite itself). What I want R to do is: 1) scan the folder to find the file. 2) if the file is a newly generated file, process the file 3) output some file identifier on the screen, such as the time when the file was

Hi all, I want to start experimenting with clusters, and I would like to use normal desktop grade hardware for this. I have some extra PC components lying around, enough to build 3 - 4 moderate desktops with a PIV / C2D CPU & 512MB - 1GB RAM each. All the machines should have at least a 100MB NIC, but I can add a gigabit NIC to the machines that doesn't have it if need be. I have used

Hello ppl, This post is to do with the variables 'nat' or 'canreinvite' for sip entities. Idealy users, wont be static, they could be roaming all over the globe. So, setting someone as behind NAT, and disabling canreinvite, etc., restricts the roaming capabilities of a user. Is there any way for Asterisk to auto detect, if a user is behind NAT, also, if two users are behind the

Nothing special, just my first plugin. it came out of a request I saw on the list from someone who wanted to be able to tell if a model''s attributes had changed prior to being saved.

Hello All, I am trying to open all files within a folder and create multiple histograms from each file, *and* have it save with the original file name plus some new information. The way I have it set up right now, I keep saving over each new graph. I can turn the history on and see them all, but I want them all to save as unique files as well.

Dear R-tisans, I am trying to calculate the 12th root of a transition (square) matrix, but can't seem to obtain an accurate result. I realize that this post is laced with intimations of quantitative finance, but the question is both R-related and broadly mathematical. That said, I'm happy to post this to R-SIG-Finance if I've erred in posting this to the general list. I've

Dear list members, does anyone have an idea why the following construction does not work but gives the following error message: assign('test', array(1:10, dim=c(10,10))) dimnames(get('test')) <- list(1:10,1:10) Error in dimnames(get("test")) <- list(1:10, 1:10) : target of assignment expands to non-language object What could be a way to get this to work?

Hello all, I have a boot server (running Debian Lenny x64) with a number of bootable options already configured (freedos, memtest, sysresccd etc). What I am struggling to do now is add Ubuntu and Debian netinst images so that I can boot from the network and have all the boot options available as if I was using a CD-ROM. The problem is that (as far as I can tell) the Ubuntu and Debian

I was wondering if anyone has put together a comprehensive list (that is reasonably maintained) that lists country codes, landline numbers, mobile numbers, etc. The particular requirement is for a dialplan to know what is going to be charged to whom. For example, mobile and landline rates are the same in the US the US has a unified numbering plan of 1NXXNXXXXXX, while the UK has: 441xxx

Hello, I’m trying to follow the syntax of a script from a journal website. In order to create a regression formula used later in the script, the regression matrix must have column names “X1”, “X2”, etc. I have tried to assign these column names to my matrix ScoutRSM.mat using a for loop, but I don’t know how to interpret the error message. Suggestions? Thanks, Paul
