Hello, A stupid question: I have an array with two columns, the first "a" acting as my index in 0.25 steps, the second one "b" the column of interest. How can i sum up "b" only for a specified window in "a" (as the window command for time series) a=seq(0,10,0.25) b=runif(41) c=data.frame(a,b) Sum up c if 3<a<5.25 How to do that? thanks marc --

Hello R, According to: g <- expand.grid(x = 1:10, y = 5:15, gr = 1:2) g$z <- log((g$x^g$g + g$y^2) * g$gr) wireframe(z ~ x * y, data = g, groups = gr, scales = list(arrows = FALSE), drape = TRUE, colorkey = TRUE, screen = list(z = 30, x = -60)) i have two wireframes in one plot. How could i change the color of the top - one to transparent (or only the grid).

Hello everybody, I'm trying to predict a linear regression model but it does not work. My Model: y = Worktime + Vacation + Illnes + Bankholidays My modelmatrix is of dimension 28x4 Then I want to make use of the function predict because there confidence.intervals are include. My idea was: mod <- lm(y~Worktime+Vacation+Illnes+Bankholidays) newdate=data.frame(x=c(324,123,0.9,0.1))

Hallo everybody. I want to build my own GO package using the function GOPkgBuilder of AnnBuilder. It uses AnnBuilderSourceUrls to collect data from different ftp sites. These data are not complete for my organism, so I would like to change the ftp adresses to a local one. The changing itself is working but when I run the script I get the following Error: Error in

Hallo! I would need a code for 10-fold cross validation for the classifiers Naive Bayes and svm (e1071) package. Has there already been done something like that? I tried to do it myself by applying the tune function first: library(e1071) tune.control <- tune.control(random =F, nrepeat=1, repeat.aggregate=min.,sampling=c("cross"),sampling.aggregate=mean, cross=10, best.model=T,

Hello When I try to install MS Train Simulator the setup.exe program switches to full screen mode. This full screen mode hides all other installer windows. The window that asks me if I want to install Adobe and the window that asks me to replace CD1 with CD2 are not visible. Therefore it is necessary to guess what I should do during the installation and do the input blindly. The main

Hi @all! I tested what happens with a file which is saved at a FAT32 partition and then this partition is converted to NTFS. So first I transfered the file with rsync from the FAT32 partition to my Linux /home folder. Then I converted the FAT32 partition to NTFS. After the convertation I transfered the file again to see what has changed (amount of data). I was surprised!!!! Nothing has changed!!!

Hi Gents, (apologizes, new here...) I didn't find any hint on G**gle nor in the Dovecot archieve (maybe due to the lack of a search function :), so: I installed Doovecot, but can't get it going.

Hi @all! Sorry about that many questions, but after searching and reading tons different web sites, I didn't find exactly what I am searching for. So, I know that with the -z Option rsync compresses the files with gzip, than the files are transfared and at the target machine uncompressed. I want to know, is there a possibility to see how big the compressed file is, which rsync generates

Sorry sending this again - is anyone familiar with multiple transparent wireframe plots? I already checked the ?wireframe, but with no examples and as newcommer its hard to find out a correct code. If we set drape=F in the example: g <- expand.grid(x = 1:10, y = 5:15, gr = 1:2) g$z <- log((g$x^g$g + g$y^2) * g$gr) wireframe(z ~ x * y, data = g, groups = gr, scales = list(arrows

Hi Samba-Group, my name is carsten from cologne. I would like to use samba/winbind in a Windows AD 2k3, 2k8 multi-domain environment as workstation. All users from the AD should be able to logon via ssh for example. It would great to use the MS userprincipalName (UPN). I am using samba 3.2.6.37 from sernet on a centos 5.2 system. The normal authentication by domain+username works fine.

Hi! I'm totally new to audio programming. I managed to create a VoIP with waveform (PCM). The problem was the really high traffic, so I desided to use speex for compressing the data. I'm recording with mono, 16bit/sample, 8000 samples per second. I tried to add the speex compression, but I always get a crash when I try to decode the data. Here is my encode and decode function: int
