Band-wise Conditional Sum - Actual problem
Dear R helpers, Thanks a lot for your earlier guidance esp. Mr Davind Winsemius Sir. However, there seems to be mis-communication from my end corresponding to my requirement. As I had mentioned in my earlier mail, I am dealing with a very large database of borrowers and I had given a part of it in my earlier mail as given below. For a given rating say "A", I needed to have the bad-wise

LLC Segmentation Fault in Matrix Multiplication
Can you attach your source code or .ll file?

Problem importing lots of records
I run a script that imports a few thousand records into the database. The script runs once for each of several XML files. What it does is parse the XML and for each element of a certain type creates a record in a rails database that gets indexed with acts_as_ferret. This worked fine before but today after a few files (70000 records) this started to happen for any file I tried:

Using rsync for two-waz-synchronisation
Hello, is there any way to use rsync for two-way-syncronisation? I want to use it to keep the data on two hosts consistent. Sometimes one of this hosts (sometimes the first, sometimes the second) changes its location. If the two hosts are at the same location I want automatically rsync them. The data only changes at one hosts but it is not defined on which host it changes. For example: I have

EADS6550 and asterisk - echo on PSTN call
Hi list, would like to know if some of you have tested asterisk connected to an EADS 6550 analogique PBX (also know as Nexpan50).

We have a setup with a T1 from PSTN going into an Asterisk box, and then out again on T1 and into a normal PBX (EADS) We use it to record all calls going to/from the PBX. The problem is that when we record the calls (with MONITOR command), DTMF tones gets obscured, and is not understood in the other end, if we dont Monitor, there are no

randomForest question--problem with ntree
Hi, I would like to use a random Forest model to get an idea about which variables from a dataset may have some prognostic significance in a smallish study. The default for the number of trees seems to be 500. I tried changing the default to ntree=2000 or ntree=200 and the results appear identical. Have changed mtry from mtry=5 to mtry=6 successfully.

Best way to connect asterisk to an traditional PBX
Hi list, we want to connect asterisk to an traditionnal PBX (EADS 6550/Matra). People from telco told that they can't connect two PBX's using E1/T1 or only with QSig signaling. I wanted to use EuroISDN. In this case, it was me told that VN6-VN7 would be used. The PBX has a spare ADQ card installed on which we would connect. Has someone a such working setup? Is it working well? More

Neat way of using R for pivoting?
Hi, I'd like to use R to do what excel pivot tables do, and plot results. I've never used R before, and I've managed to do something, but it's quite a lot of code to do something simple. I can't help but think I'm not "Doing it the R way". I could be using R for the wrong thing, in which case, please tell me off. I was hoping something like plot(by(t,
