[BioC] feature selection

[Karen.Chancellor at asu.edu]

Hello Bioconductor folk,
Can any of the bioconductor packages be used on a .pcl file, rather than
starting with the raw data?
I am starting with a .pcl file containing approximately 900 genes and 50
samples, which I have read using read.table. The classification is known, and
there are 3 classes of samples. I am interested in reducing the number of
genes. I would like to use the R RandomForest package for this task. 
Is this appropriate? I'm new to this so will appreciate any help.

Thanks
Karen
