...sing cross-correlograms or cross-variograms. Is this an option in one of the R-packages? I've been searching the R-help archive and the available package-documentations, but I can't find how to do this. Thanks in advance, Ren?. _______________________________________ Ren?

...n error message "can't run the model with multiple levels", or something alike.. Is there a way around this or should I start looking fo another way of analysing the data? Thank you for your time.

Im developing an application with R and Gtk+. It's just a simple GUI which helps new users to interactuate with R. Thing is, when you do a statistical analysis, I also want to provide a HTML report, but HTMLStart doesnt work propperly when executing from TinnR. It does create the file but not empty, I've tried some examples from different websites, and it's always the same.. it works

Can someone help me with performing leave-out-one cross validation using R (model built is a Cox model)?

...ution, I need to do this with multiple data.frames that slot-wise are identical, but each slot length is different between data frames. Seems like there should be an easy solution, but I just have not stumbled across it in the documentation. Thanks, John C. Sweval Database Architect Illumigen Biosciences, Inc.

Hi, My R version is old, and I would like to update it. How can I update R and keep all the libraries? Thanks Best, Yunfei Li -------------------------------------------------------------------------------------- Research Assistant Department of Statistics & School of Molecular Biosciences Biotechnology Life Sciences Building 427 Washington State University Pullman, WA 99164-7520 Phone: 509-339-5096 http://www.wsu.edu/~ye_lab/people.html [[alternative HTML version deleted]]

Hi, I would like to have an index for a column in a matrix encoded in a cell of the same matrix. For example: x = matrix(c(11,12,13,1, 21,22,23,3, 31,32,33,2),byrow=T,ncol=4) In this case, column 4 is the index. I then access the column specified in the index by: > for (i in 1:3) print(x[i,x[i,4]]) [1] 11 [1] 23 [1] 32 > > for (i in 1:3) {x[i,x[i,4]] <- x[i,x[i,4]] + 5} > x

I would like to prepare the data for barplot. But I only have the data frame now. x1=rnorm(10,mean=2) x2=rnorm(20,mean=-1) x3=rnorm(15,mean=3) data=data.frame(x1,x2,x3) If there a way to put data within a specific range? The expected result is as follows: range x1 x2 x3 -10-0 2 5 1 (# points in this
