...#39;TA' are essentially the same, and I'd like to combine (add) the rows to reflect this. The final matrix should be: [,1] [,2] [,3] [,4] AA 1 5 9 13 AT 5 13 21 29 TT 4 8 12 16 Is there a fast way to do this? Thanks in advance!

Dear R-list, I apologize for my many emails but I think I know how to desctribe my problem differently and more clearly. My question is how to compare linear models with intercept and those without intercept using maximizing adjusted R^2 strategy. Now I do it like the following: > library(leaps) > n=20 > x=matrix(rnorm(n*3),ncol=3) > b=c(1,2,0) > intercept=1 >

Hi, I have a file: d:\foo.txt and want to delete this. I tried: system("del d:/foo.txt") works not system("notepad d:/foo.txt") works Is it possible that I can't delete files or do I have misunderstood something? (del is a DOS-command. The "string works" under DOS "\") Thanks a lot Thomas ----- Windows XP R 1.6.2 (update!, I know)

Hi R-hackers I try to write a batch (in Windows, i have to use!) with Rcmd BATCH D:\Test.R D:\Test.Rout and Rterm.exe --no-restore --no-save < D:\Test.R > D:\Test.Rout. In my file Test.R are any tk-codelines (like: Window1 <- tktoplevel(); ... tkbutton...). It works not interactifly, what is written in Rcmd BATCH --help. Exist there a way to do it all the same? Please help...

Hallo, I just made a boxplot with the following command: boxplot(vsnrg$M~col(vsnrg$M)) When I now look at the plot. On the x-axis I just find numbers 1-6 because I have 6 datasets plotted. Now I want to add there the corresponding names which can be found in colnames(qrg). How can I realize this the online help does not help me. Thanks Corinna

I know my subject line seems odd, but I want to replace an expression—such as a variable—with its value. For example, I want to paste() some strings together, assign the result to a variable s, then use the value of s as a variable to hold another value. Something like this: import_subjects <- function (start, iterations) { for (i in 1:iterations) { # iterate from start to end s <-

Hi r-hackers, What exactly is the difference in call r from a batch between this two ways: Rterm.exe ... Rcmd BATCH ... (I have to install perl first, I know) I haven't found any documentation about the difference (readme, FAQs, ...). I use rterm.exe, but is there a benefit in using rcmd? Can you explain me that or give me a link? Thanks Thomas Thomas Untern?hrer

Hi, Does anybody has a simple example (a for loop, or so) how to use a C-function In R? If it's possible, a *.cpp-file and what I need (wrapper or what ever). I'm absolutly not a C++-hacker! I try several ways, was reading the "writing R extension" and the windows-FAQ, but failed. I try to programm a matrix inversion in a for-loop in C, which needs much time in R and want to

Hi, Does anybody knows a easy way (without for-loops, maybe with something like match) to solve this problem: x <- rep(1,3) y <- c(0,1,0,1,0,1,1,1,0,0,0,0,1,0) if (x is a part of y){ find out where it is and do something } Thanks a lot Thomas

Hi, Is there no function in R similar to jpeg(...) or postscript(...) for windows meta files? The function savePlot(...) is not really what I need. I'd like to save the plot on my disk without open a new plot window. And I don't want to save it on my disk and convert it from a *.* to .wmf (there are too many). Thanks for any help Thomas

hi, two questions... 1. what happens with points()? after the split.screen function points() start not at x = 1 (at x = - something) graphics.off() x11() split.screen(c(3, 1)) split.screen(c(2, 1), 1) screen(3) plot(dat, type = "n") screen(4) plot(dat, type = "n") screen(2) plot(dat, type = "n") dat <- rnorm(1000) for (i in 1:length(dat)){ screen(3)

One possibility ist boxplot(sapply(ListOfNames, get, env = .GlobalEnv)) Hope that this helps Thomas -----Urspr??ngliche Nachricht----- Von: Lefebure Tristan [mailto:Tristan.Lefebure at univ-lyon1.fr] Gesendet: Mittwoch, 7.

hi people, I am a newbie to R and I would appreciate it very much if someone can help me. I am used to use SPSS so I don?t have experience with writing a script. I have a questionnaire (questions 1-12) and I would like to use the omega reliability. Question 1-8 is factor 1 and question 9-12 factor 2. How can I write the scripit? Can someone help me??? Thanks in advance Asterios
