the sample() function
hello R-Wizards!!!!! again i'm invoking your presence!! since all the fuss about the paradoxes on a computer algorithm generating "caos" or un-determinancy, i recently grew quite curious about the mechanism underlying the procedure of NUMBER RADOMIZATION. could anyone of you, masters, attach me the algorithm (or source code? is it right?) behind the *sample()* function, so i can

windowing strategies
Hello to everybody, Does anyone has implemented a function for evaluating models using windowing strategies, such as growing window or sliding window ones? The aim is to evaluate regression models on a time series data. I do not use cross-validation once data sorted in a radom way does not make sense when evaluating time series. Thanks Joao Moreira

AGI global style variables
I have had some radom occurances of someone calling in, and for whatever reason the person is getting dumped into the section of the lcr.agi file that output the message of "it is necessary to dial x". I was curious, does any one know about a variable that might be available in the AGI that would tell me what channel they are coming in on. I looked in the wiki and found

SATA
Has anyone had any problems with SATA, either on board or 3rd party setup? I've currently got a problem where an AMD non SATA FC2 system is working fine but an Intel system with a 3Ware SATA card and FC3 is radomly not syncing with the ISDN30. It allows and receives calls but at random intervals drops them. Regards Lee -- No virus found in this outgoing message. Checked by AVG

Extremely slow during browsing some directories

I use the SHARE security level to make things easier. Everything goes fine so far, except that for some windows user, some times, on browsing some directories, it takes extremely long time to display the

restricted bootstrap
Hello List, I am not sure that I have the correct terminology here (restricted bootstrap) which may be hampering my archive searches. I have quite a large spatially autocorrelated data set. I have xy coordinates and the corresponding pairwise distance matrix (metres) for each row. I would like to randomly sample some number of rows but restricting samples such that the distance between them is

How to best start from scratch implementing a ERM diagram?

Should I first create all tables without foreign key? Should I just start somewhere and add them radomly? I''m

Steam Apps freezing
I'm using wine to run Steam based games like Counterstrike and Day of Defeat. This generally works well but from time to time the games radomly freeze(about every hour or so). To get further information I made an error.log(see below) and googled the error. I found quite some information but no way to solve the problem. Any ideas, assumptions...? ##Information on the system## Linux

Red X and guest user message in logs
Hello, I have a Debian Sarge machine running Samba 3.0.14a as PDC and file server. Everything runs smoothly, except for a random problem: users (on Win2000Pro clients) are often seeing a red cross on the main network share, as if it was disconnected. This red X seems to come and go at random. The red cross would not be a big issue itself, but it has an annoying consequence: when it appears,

"Unable to find path from G729A to ULAW" on Sipphone.com
I seem to be having a problem with transcoding and/or agreeing on a valid codec. I am running a new image pulled from CVS at 1:30 PM CST. The issue occurs when I try to make a call to a toll-free number over sipphone.com. Here's what I see in the console: NOTICE[1259545280]: File channel.c, Line 1478 (ast_set_read_format): Unable to find a path from G729A to ULAW NOTICE[1259545280]: File

asterisk and iptables
Hi, I have a problem with asterisks on Linux. Looks like it is a iptables problem. My external client (eyebeam, on a different computer) cannot register to the asterisk server, but the asterisk server itself *looks* working. If I dial one of the incoming phone numbers for the server, I can see the call arriving in Asterisk (using asterisk -r). I tried nmap on my server, and this is the result:

potential wiki on encryption
Hello all, I posted the whole disk encryption instructions in the forum that has been briefly discussed on the list.

Encrypting tmp swap and home
Hi everyone, I added a page under the HowTos for Encryption, and then added a guide for encrypting /tmp /swap and /home using cryptsetup and LUKS keys on LVM, when you already have partitions setup. http://wiki.centos.org/HowTos/EncryptTmpSwapHome Regards, Max
