Re: [R] read.table

Sorry for last post. I don't know why i got the error message last time. but if i did in the following way: t-scan('train1.dat', sep='|', na.string='.') t2-matrix(t, nrow=195, ncol=273529) t3-t(t2) t4-as.data.frame(t3) now I got what i needed. Thanks a lot for Gabor's prompt help. weiwei On

[R] Proportion test in three-chices experiment

Hi, I wish to analyze with R the results of a perception experiment in which subjects had to recognize each stimulus among three choices (this was a forced-choice design). The experiment runs under two different conditions and the data is like the following: N1 : count of trials in condition

[R] help: how to get the position of a value in a matrix

Hello, I have a data set matrix of 1200 * 15. How can I get the position of a specific value in the matrix? I use seq(along = x)[x value] to look for the position of the value in the matrix, but seq can just find the sequence position row by row in the matrix, not a real position (like

Re: [R] Efficient testing for +ve definiteness

My preference is to test see if the smallest eigenvalue is less than something like sqrt(.Machine$double.eps) times the largest. This may be too conservative, but if the ratio of the smallest to the largest is less than some small number like that, the inverse of such a real

Re: [R] Memory question

What kinds of matrices? There are facilities in the Matrix and SparseM packages that might help for sparse matrices. If they are N x k where N is large and k is not, can you compute something like the QR decomposition and get away with keeping only the R part for most of your

[R] anova.lmlist output change

R-colleagues I have adapted the anova.lmlist function to use the model object name as the first column in the output instead of the string Model n. If there is general agreement can the change be implemented into the stats package? Regards Ross Darnell -- University of Queensland, Brisbane
