Hi Robert, Thank you for your prompt reply. I had a closer look at the function and documentations on partial least squares. Would you please help me update the ' glpls1a' function in the 'gpls' package, so that it returns the internal variable capital 'P'? This will give me the loadings matrix, which is similar in concept to the principle components in principle component analyses. Thank you in advance.

I don't know if it is correct - you can look at W when running the function (use R's function debug) and once you are sure you know what you would like to have returned I would be happy to modify the package. best wishes Robert > > > > Regards, > > > > Ignatius > > > > > > Ignatius Pang > > PhD, Biotechnology, UNSW > > NSW Systems Biology Initiative > University of New South Wales, Sydney, NSW, Australia, 2052 > > i.pang at unsw.edu.au | www.systemsbiology.org.au > <http: www.systemsbiology.org.au=""/> > > > > > > > > > > > ? ? ? ?[[alternative HTML version deleted]] > > _______________________________________________ > Bioconductor mailing list > Bioconductor at r-project.org > https://stat.ethz.ch/mailman/listinfo/bioconductor > Search the archives: > http://news.gmane.org/gmane.science.biology.informatics.conductor > -- Robert Gentleman rgentlem at gmail.com
