Dear Olivier, This issue has been asked a couple of times on the email list before. I am attaching a few messages from previous postings that I have kept around, but it might be a good idea to search the archives (I am almost sure there were more messages). I also have some R code, which is basically a quick and dirty R implementation of the matlab code in the paper by de Jong, Wise, Ricker, 2001, J. Chemometrics, 15: 85-100, plus a few other things; but there is no help, etc, though the code is somewhat commented.
Best, **************************************************** Re: [R] Partial Least Squares Date: Mon, 4 Nov 2002 11:39:43 +0100 From: Stephane Dray <[EMAIL PROTECTED]> To: [EMAIL PROTECTED] >Hi everybody! > >Is there any package or functions to make Partial Least Squares >analysis with R? I don't know.. I have a function to perform NIPALS (Nonlinear Iterative Partial Least Squares). This is an alternative for PCA based on PLS which can be cery useful in the case of missing values. Sincerely. ********************************************** Date: Mon, 04 Nov 2002 10:51:45 +0000 From: Peter Ho <[EMAIL PROTECTED]> To: Luis Silva <[EMAIL PROTECTED]> Cc: R help <[EMAIL PROTECTED]> Luis, You can find Ron Wehrens chemometrics toolbox for R at http://www-cac.sci.kun.nl/people/rwehrens It includes PLS and LDA. Alternatively, you may be interested in checking out Julian Faraway's book Practical regression and ANOVA in R at http://www.stat.lsa.umich.edu/~faraway/book/ There is a section on PCR and PLS.
