R help - Nov 2012 - SVM? Comparison method wanted: 3 Groups, Microarray data

Dear all,
i have microarray data of 3 classes of patients. It's not a time course
experiment only steady state.
I used a rule-based method to classify the groups by the expression of the
genes. This works out so far. Nevertheless I want to check my results with an
other method. Therefore I look for one and want to ask you, what you suggest.
I have 3 different patient groups, only the steady state data, 10/10/13 (total
of 33) arrays and the challenge is to classify the groups by the expression of
all genes on the hgu133a chip.
The named rule-based method found for each group genes, which explain a
classification for each sample to one of the groups.
Are there packages/method you can suggest? I guess PAMR works not so good for
all genes on the chip, right?
Would be amazing if you can tell me your opinion.
All the best and thanks
Peter
