[R] permutation test for PLS/PLSDA

Hi, Is there any R package doing permutation/randomization test for PLS/PLSDA? I found some codes for MatLab, but I want to use R program. Thank you very much in advance. Kohkichi Hosoda __ R-help@r-project.org mailing list https://stat.ethz.ch/mailma

Function strptime() will convert the date-time character string to a POSIXct object that you can use in your plot. In general, when posting a query to r-help: 1. Do not use html, only plain text (see what happened to your data below. 2. Use dput() to convert your data to a form

Re: [R] creating a function

Hello, It's a bad idea to name a function and one of it's arguments Y, use Yfun and Y. What does summation(x(Y.t, Y.t-1, ...)) mean? Is there a multiplication sign between x and (Y.t, ...)? And is epsilon a vector of errors, one for each Y.t? If so, the following might do it. Yfun <- function(

Re: [R] Does R have an equivalent for Matlab's cell array?

Data frames are lists of vectors. You can have the vectors in a data frame be of mode list, if you wish. It would be more conventional to simply make the list and not put it into the data frame, since columns of mode list give write.table fits. I prefer to simply keep the first form of your dat

Well, you could try it to see what happens... First look at: b$ansologin%in%quit then !(b$ansologin%in%quit) and finally b[!(b$ansologin%in%quit),] You could also read the help ?"!" ?"%in%" and the Intro to R manual that came with R when you installed it. Sarah On Sat, Dec 22, 2012 at 10:48 AM
