Dear list, I would like to start some R workshops at King's College London, and to do so, I would like to use the "Use R!" logo at http://www.agrocampus-ouest.fr/math/useR-2009//useR%21%202008_fichiers/useR-middle.png Since it seems to be difficult to get a shell account at KCL, I also went ahead and registered use-r.org.uk and am starting to put together a website at

Dear R users, I create a graphic with two plots side by side using layout(), like this: layout(matrix(c(1,2),1)) plot(1:10,main="left plot") lines(c(3:7,7:3),col="red") plot(10:1,main="right plot") The lines() obivously get added to the "left plot" plot. Now, I'm trying to write a function that builds up a plot bit by bit to then include it in a

Dear list, I have data like this: dat1 <- data.frame(subject=rep(1:10,2), cond1=rep(c("A","B"),each=5), cond2=rep(c("C","D"),each=10), choice=sample(0:1,10,replace=TRUE)) I would like to compare subjects' "choice" for (cond1=="A" & cond2=="C") vs

Dear Rers, I have a function to barplot() a matrix, eg myfun <- function(x, ...) { barplot(x , ... )} (The real function is more complicated, it does things to the matrix first.) So I can do: m1 <- matrix(1:20,4) myfun(m1) myfun(m1, main="My title") I'd like to be able to add the number of rows of the matrix passed to the function to the "..." argument, eg

I have two lists of the same shape, like this: x <- list() x[[1]] <- c("one","two") x[[2]] <- c("three","four","five") y <- list() y[[1]] <- c(TRUE,FALSE) y[[2]] <- c(FALSE,TRUE,TRUE) I would like to index x "by" y, that is, the result in this case should be: z [[1]] [1] "one" [[2]] [1] "four"

Dear list, I have a file that is comma delimited but contains some erroneous non-delimiter commas. I would like to replace these commas with semicolons and then read the correct file into R as a data frame. I want to do this from within R, without changing the original data file. My current idea of how to do this would be to use system("sed ...") and feed the result to read.csv(), but

Dear list, I have two vectors: x <- c("one","two") y <- paste(rep(x,2),"blah") I want to replace all occurrences of each element of x in y with something else, so that y looks like this: y [1] "something else blah" "something else blah" "something else blah" [4] "something else blah" I can do this using a loop: for (

Dear R users: Maybe it is a silly question, but I'm don't understand what am I doing wrong. In a new karmik koala ubuntu installation I compile the last patched 2.10.1 version of R. Every thing was right (I install all the dev libraries I need). First I type: ./configure --enable-R-shlib And I obtain: R is now configured for i686-pc-linux-gnu Source directory: .

Dear list, I've written a function that plots subjects. Something like: myplot <- function(subject) { plot(subject) } Subjects are vectors, e.g. ... s1 <- c(200,200,190,180) ... and plotting them works fine, e.g. ... myplot(s1) Now I want to have "s1" etc appear in the plot title, but I don't know how to refer to this generically (the object "name"? I tried

I have been looking at a draft of Doug Bate's book on mixed effects models (http://lme4.r-forge.r-project.org/book), and in chapter one (section "1.4.2 Matrices and Vectors in the Fitted Model Object", to be exact) he refers to the function env() for checking the environment of a fitted lmer object. This function does not appear under help, and I have not been able to find

Hi list, I have data in a dataframe t1, with a column for different amounts spent, a column what it was spent on, and a column with dates, from which I create a new column with months. Example: amount <- rep(c(10,20,30),3) what <- rep(c("food","books","cycling"),3) when <- c(rep("2008-09-05",5),rep("2008-10-07",4)) t1 <-

Hello, I am doing a simple if else statement in R. But it always comes out error such as 'unexpected error' There are two variables. ini and b. when ini=1, a=3; when ini>1 and b>2, a=5; all other situations, a=6. I don't know where it is wrong. Here is my code ini=3 b=4 if (ini==1) { a=3 } else if (ini>1 and b>2 ) { a=5 } else {a=6} Thanks a

Dear All, I have a data frame with 5 column and 201 row data. I want to add one more column between column 1 and 2 with value of 1. So the new column has to be the second column filled with 1. Any help will be appreciated. Thanks for your time. Thanks & Rg Mohan L

Hi to all, test <- data.frame("X"=c(1:4),"Y"=c(5:8),"Z"=c(8:11)) test <- test[,-2] Is there a way to specify the col name "Y" to delete instead the number? Kind regards Knut

Hi, I want to use the .RProfile to set defaults such as text editor. Is this a file I need to create? Also, where should I put it? I tend to create .RData files for different projects, putting each in a different Windows (Vista) folder. Is one .Rprofile file created that any instance of R can access (I would imagine so)? Thanks, Walt -- ________________________ Walter R.

Hi, I have a qplot like the one in the minimal example below, except I also have faceting like this: qplot(jitter(Goodall),jitter(Better.adapt),colour=Second.adapt,facets=~Pol,data=d1) and with the real data I get quite a lot of overplotting, so I would like to add an alpha channel. In addition, I would like to be able to control which colors are used for each value of Second.adapt (which
