[BioC] How to generate bar files?

[Susan Wilson]

Hi,

Does anyone know how to generate bar files with rMAT? 
help(NormalizeProbes) says "The output can be saved as BAR file if the 
BAR argument specifies a filename, or as a parsed BAR file if argument 
output specifies a filename."

Other than that, I cannot find anything relevant.

Thanks.
Susan
