similar to: env() for lme4

Dear R users, I recently downloaded the library lme4a by svn checkout svn://svn.r-forge.r-project.org/svnroot/lme4. I tried to install the library lme4a by copying the downloaded document in the location where all the R libraries are saved. When I try to load the library, I obtain the message library(lme4a) Error in library(lme4a) : 'lme4a' is not a valid installed package R version

Hello dear friends. How can I make ubuntu to move from version 2.13.1 of R software to version 2.12.2. I want to go down to the less advanced version to use the package "lme4a". Please, I need your help. Thank you in advance.

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

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 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 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

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 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

I read somewhere (help list, documentation) that the random effects in lme4 uses sparse matrix "technology". I'd like to confirm with others that I can't use a sparse matrix as a fixed effect? I'm getting an "Invalid type (S4) " error. Thanks. ~~~~~~~~~~~~~~~~~~~ -Robin Jeffries Dr.P.H. Candidate in Biostatistics UCLA School of Public Health rjeffries@ucla.edu

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

Hello, I am doing a if else statement in R. But it always comes out error such as 'unexpected symbol' There are two variables. ini and b. when ini=1, a=3; when ini>1 and b>2, a=3; 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=3 } else {a=6} Thanks a

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: .
