Is there a modulus operator in R? Anna

...<- cbind(z,p) } z <- na.omit(as.vector(t(z))) } and then sections(32,5) -> a As I see it, rows in result are 5 and the vector length of p (which is 5) is a multiple of 5. kind regards, Paul -- Paul Lemmens NICI, University of Nijmegen ASCII Ribbon Campaign /"\ Montessorilaan 3 (B.01.03) Against HTML Mail \ / NL-6525 HR Nijmegen X The Netherlands / \ Phonenumber +31-24-3612648 Fax +31-24-3616066

I've started a "tribe" for discussing R and sharing scripts. Tribe.net is one of the popular on-line social communities, like "Friendster". Visit and see if it is a forum that you find useful. To join the "tribe" you will need to register with Tribe.net. I hope it will be of help to newbies, although I'm new to R myself. Here is the url:

I'm puzzled by the following problem, which appears when attempting to run an analysis on part of a dataset: If I try: csubset <- dat$Diagnosis==0 cont <- lme(fixed=cform, random = ~1|StudyName, data=dat,subset=csubset,na.action=na.omit) Then I get: Error in eval(expr, envir, enclos) : Object "csubset" not found But if I do

...ethod B I still need to 'dd$c <- dd$c[, drop=TRUE]', while the manual seems to imply that with the drop argument to subset() this would not be necessary.

Hi! I have a 3d array: > dim(ib5km15.dbc) [1] 190 241 19 and a set of positions to extract: > ib5km.lincol.random[1:3,] [,1] [,2] [1,] 78 70 [2,] 29 213 [3,] 180 22 Geting the values of a 2D array for that set of positions would be: > ima <- ib5km15.dbc[,,1] > ima[ib5km.lincol.random[1:10,]] but don't find the way for the case of the 3D array: >

Hi, I would like to know if it is possible to get printed output while a loop is taking place. Example: for(i in 1:10){ print(i) some long process } This will print the values of i only after the loop is finished, what I would like is to see them when the process enters the i-th iteration to keep track of how the program is running. Thank you, Gilda

Hi I have two basic questions, and here they go, but I was wondering as well where can I ask these basic questions without bothering you people I've used Splus and now I'm using R and there's some functions that I can't simply find one: sort.col that allows data.frames to be sort by a given col (I saw the funtion sort but that's for vectors. and I can't believe I

Hello, I would like to access my data frame without one variable. E.g.: > colnames(x) [1] "Besch" "Ang.m" "Arb.m" "i10" "Umsatz" "arbstd" I can try x[,-1], but this variable must be called by it??s name. x[,-"Besch"] x[,!"Besch"] attach(x) x[-Besch] ... ... does not work. I could not found a solution of

I want to read data from a number of files into R. Reading individual files one by one requires writing enormous amount of code that will look something like the following. **************** maptools:::dbf.read("wb-01vc.dbf")->dist1 maptools:::dbf.read("wb-02vc.dbf")->dist2 maptools:::dbf.read("wb-03vc.dbf")->dist3

Dear ALL, I fear my question has already been answered many times before, but I haven't fund that in archives... I am working on spatial datasets and, in most arrays I'm handling, there are two columns dedicated to (x,y)-coords. For different reasons - notably to draw image() plots, I need to have these two columns sorted in increasing order. But sort() and order() seem to apply to

Dear all, I hope to remove a whole column from a data frame or matrix (> 2000 columns). All value in the column are same. The first thing is to select those columns. For instance, I hope to remove the V3~6 column, for all the value in those colume is zero. V3 V4 V5 V6 V7 V8 V9 V10 1 0 0 0 0 0.000 0.000 0.000 0.000 2 0 0 0 0 0.000 0.000 0.000 0.000 3 0 0 0
