Dear all, i searched for a classification method for microarrays with 3 groups. Therefore I found the package "PAMR" which works out for the example data and with the tutorial ( http://www- stat.stanford.edu/~tibs/PAM/Rdist/doc/readme.html ) Well, i tried it with my data and the output is not so good as expected. So I asked myself if there is any limitation regarding the numbers of genes for the input . Are there any experiences regarding the input/gene numbers? If there are any methods/scripts for classification of three diseases, please let me know. All the best and thanks Peter

Thanks Sean, but i guess: The included methods are not so different to methods in the e1071-package. I guess: For thousands of genes it is a little bit difficult or? Maybe I have to choose an other method. You suggest one?

You might want to look into the 'CMA' Bioconductor package or the 'bootfs' package on CRAN if classification is your goal.
