Hey, all Will u please tell me how to input a matrix (n x m) A in R? I cannot find such commond in the manual.
Weird. I found it hard to miss. Where did you look? By "input" what do you mean? Type it in from the R-prompt, or read it off a disk, download from a url connection, load it from a database server, copy it from an SAS export file, or ... I think the two most likely questions you're trying to ask are 1) type it in. For example: A <- matrix(c(1,2,4,5,6,9),nrow=2) 2) read it off disk. For that, you'll need the R Data Import/Export Manual that came with your R distribution. If you can't find that, look here: http://cran.r-project.org/doc/manuals/R-data.pdf Cheers Jason
