Hi My name is Vladimir Samaj. I am a student of Univerzity of Zilina. I am trying to implement Kalman Filter into my school work. I have some problems with understanding of R version of Kalman Filter in package stats( functions KalmanLike, KalmanRun, KalmanSmooth,KalmanForecast). 1) Can you tell me how are you seting the initial values of state vector in Kalman Filter? Are you using some method?

Dear R-er, I would like format integer number as characters with leading 0 for a fixed width, for example: 1 shoud be "01" 2 shoud be "02" 20 should be "20" Now I use: x <- c(1, 2, 20) gsub(" ", "0", format(x, width=2)) But I suspect more elegant way could be done directly with format options, but I don't find. Thanks a lot Marc

But when i try to run any 3D app through wine it fails with for example: $ wine Oblivion.exe fixme:mixer:ALSA_MixerInit No master

You mean you used your bsd-ports-provided gcc to compile LLVM and you've got 4 times a bus-error during the build? In this case, it cannot be a LLVM problem. In the linux-community, people say that bus-error's are

Hi, Problem: When talking to someone (from pstn) and this person is not talking loud, the voice is cut by Asterisk. I tried increase RxGain but it changed nothing (was talking louder but voice still cut.) I use XLite as soft phone. I think this is probably a codec setting... but how do I check that on server side? I just don't know what to do. All works fine (asteriskathome) but I always

OK, wanted to check out the macosx driver for libao on me new iBook. Everything compiles beautifully (given some utils from the fink project, like automake), but... but the dynamic plugin system is broken. 1) on OS X, dll's en in .dylib, not .so, as is hardwired in. this should be an easy fix. 2) dlopen chokes on opening the .dylib files...so the plugin is never loaded. i know not enought

Debugging the memtest86+, the check at main.cpp function static void parse_command_line(void) if (*OLD_CL_MAGIC_ADDR != OLD_CL_MAGIC) return; Is being evaluated to true. What should I do? There is a way to instruct memtest to use the "old way" to pass

Hi, I have a cronjob that executes a script that has some echo statements in it and the commands in it also generate output (it copies files, reloads services, etc...).

Dear R-users, I have some very simple data where 1's represent events and zeroes non-events, e.g. temp <- rbind(c(0,1,0,0,1,1,1,0), c(0,0,0,1,0,0,0,0)) For each row in the matrix, I would like to replace a singelton event by a 0. That is, any 1 surrounded by zeroes (010) should be replaced by a zero (000). Sequences of 1's should be left unchanged. So the modified matrix shoud look

Dear R users: I have two set of data, as follow: x<-c(0,0,0.28,0.55,1.2,2,1.95,1.85, 1.6,0.86,0.78,0.6,0.21,0.18) y<-c(0,0,0,0.53,1.34,1.79,2.07,1.88, 1.52,0.92,0.71,0.55,0.32,0.19) i<-1:length(x) I want to sum each (x[i]-y[i])^2/x[i] together, like: >Sum <-sum((x[i]-y[i])^2/x[i]) >Sum [1] NaN Because the denominator shoud not be zero. So I want to overlook those

Hi all! Is there a way of logging date/time/workstation/username for every logon and logoff in a samba domain? I realized that it isn't possible to use log level auth for this purpose. I tried to use connections to netlogon service written on the logs. But I realized that those connections are closed before the user logs out. The main idea behind this is to have information enought to
