R help - Mar 2007 - Need suggestion regarding analysis of high dimensional data

Hi,
 I have two matrix of high dimension representing data for two classes. The
matrix are of 1500 columns, each column represent one feature.
 
 Is it possible to extract the discriminating feature and non-discriminating
feature by applying lda from MASS library. Or is there any other library which
can do the same.
 
 Regards
