Dear all, I have a problem with the "subset()" function. I spent all day yesterday with a collegue to solve it and we did not find a satisfying solution (even in the archived mails), so I ask for your help. Let's say (for a simple example) a matrix mat: R> mat cola colb colc [1,] 1 4 7 [2,] 2 5 8 [3,] 3 6 9 My goal is to select the lines of the matrix on the basis of the

Dear all, Once again I need your help ; I fond a way to do what I want but I am sure there is a better way.. maybe you can help me. I have a matrix, for example mat.tot : > mat.tot ID Desc M1 M2 1 1 gene1 0.5 0.2 2 2 gene2 -0.4 -0.1 3 3 gene3 1.0 1.2 4 4 gene1 0.6 0.3 5 5 gene2 -0.3 0.0 and I want to merge line 1 with line 4, and line 2 with line 5 because this is the same gene. I can

I think I must be missing something obvious, but I'm having trouble getting a data transformation to work on groupings of data within a data frame (csss3) as defined by 2 factors (population, locid). The data are sorted by year within locid within population and I want to lag another variable (dbc), i.e, shift them down by 1 row replacing the first row with NA, within groups defined by

Hi, Since C++ code compiled with g++ 4.6.3 on Windows (the version included in latest Rtools) now can produce things like '1.#IND' when writing doubles to a file (using the << operator), I wonder whether scan() shouldn't support those things. Right now (with recent R devel and latest Rtools) we get errors like: Error in scan(file, what, nmax, sep, dec, quote, skip, nlines,

Dear R users, I want to check matrices when i change the order of the rows or/and the order of the columns or/and the combination of them i will give an example what i want  1  -1  1  1      1  1   1  1 -1  -1 -1 -1    -1 -1  -1  -1   1  1    1  1     1 -1    1   1 these 2 matrices are identical because i change the first row and make it third   1  -1  1  1      -1  1   1  1 -1  -1 -1

Dear all, We are facing this problem for long, and so ask for your help. We are plotting 2 graphs in a postscript device (left part -layout function-), and the common legend for these graphs on the right part. The legend in the postscript device looks ok: this is color lines with numbers on the right (6 columns) , see the code below: > nblock<-c(1:48) > leg<-paste(c(1:npin),"

Dear R-users, after trying and searching a long time i have the following question. is it possible to replace to following double loop by some apply calls? ####################################################################### m1 <- data.frame(v1=factor(letters[1:5]), v2=factor(letters[2:6]), v3=factor(letters[3:7])) m2 <-

hello everyone. Look at the following R idiom: a <- array(1:30,c(3,5,2)) M <- (matrix(1:15,c(3,5)) %% 4) < 2 a[M,] <- 0 Now, I think that "a[M,]" has an unambiguous meaning (to a human). However, the last line doesn't work as desired, but I expected it to...and it recently took me an indecent amount of time to debug an analogous case. Just to be explicit, I would

Dear all, I would like to be able to store multiple graphs in one ps or pdf file, but I cannot achieve this only if I don't shut the "postscript" device between the graphs. here is what I managed to do : > postscript(file="test_graph.eps", onefile=TRUE) > plot(1:10) > plot(1:20) > > dev.off()

Dear R-helpers, I am running well Perl and R on my Debian Linux, and I tried RSPerl. Installation is ok and all simple functions run well. But I have a problem to call the "lines" function. I would like to draw an histogram with the density curve on. Is is OK in R with the command: >x<-rnorm(1000) >hist(x,prob=T) >lines(density(x)) for example. Now, I have a Perl script

What is a smart way to change an entry inside a column of a dataframe or matrix which is of type "factor"?

Hi All, I would like to ask two questions about printCoefmat(). First, I found a behavior of printCoefmat() that looks strange to me, but I am not sure whether this is an intended behavior: ``` r set.seed(5689417) n <- 10000 x1 <- rnorm(n) x2 <- rnorm(n) y <- .5 * x1 + .6 * x2 + rnorm(n, -0.0002366, .2) dat <- data.frame(x1, x2, y) out <- lm(y ~ x1 + x2, dat) out_summary <-

Dear all, I try for long to understand exactly what is the factor type and especially how it works, but it seems too difficult for me.... I read paragraphs about it, and I understand quite well what it is (I think) but I still can't figure how to deal with. Especially these 2 mysteries (for me) : 1st when I make a dataframe (with the as.data.frame() or the data.frame() commands) from

Just replied to another thread with the same problem... This is on a member server, not the DC. No the second chgrp command with the escaped space doesn't work.
