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

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 <-

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

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 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 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

Hi! Is it possible to start R by clicking the .RData file in linux as in Windows? I've tried with ubuntu hardy using the right button and selecting R, but does not work. Is there any way to set it up? (I know R can by started from the terminal, selecting the appropriate directory).

Please forgive me if this has been asked before but I could not readily find an answer. First, from the example I was able to determine that graphics device commands such as plot can be redirected using 'png' and 'bmp' type commands. I tried this and it works as I understand it. The question is how this graphics device works. If I issue another 'plot' command will it also

I've been trying to set my email setting to Digest Mode for a while, but it doesn't seem to "take". I log through to the "Unsubscribe or edit options" button on the Web interface to the R-help mailing list page. I scroll down to the "Set Digest Mode" box and change the radio button to "On". I click the "Submit My Changes" button

Dear All, a short and maybe simple question: I have to rank all values in a matrix from 0 to X, [1] [2] [3] [4] [1] 0.1 2 0 3 [2] 50 3 3 1 [3] 100 1 1 0 [4] 100 2 2 0 0->0 0.1->1 2->2 3->3 50->4 100->5 (X=5) is there any function for this? i have looked in several packages (vegan, labdsv etc.) because I am working with species by site tables,

Hi, I just installed R, I'm work in UBUNTU and I don't have idea about how to run a r-code written in emacs into the shell. Well I am in a shell, and obviously I can run simple commands over there, Must I compile the program? if yes, How must I do that? what is the extension? I really appreciate your help -- View this message in context:

Hi, Appologies for the simple nature of this question, I am unable to find the answer in manuals (EG and introduciton to R). I have written a function in a text editor and saved it with an .R extension. It is saved in my working directory. How can I run it, do I need to use source? If so, how do I supply the arguments to the function? Or does it need to be saved in a particular directory?

Dear R-people, I want to use an idea from LaTeX in the work flow with R. It is possible in LaTeX to have a main file from which other files are called (ie included). So for example if you have book, the main index file would call each chapter separately. Is there something comparable in R that follows the above 'include' idea from LaTeX? A main file that calls parts of an analysis or
