[BioC] More than one weight with marrayRaw class

[Jean Yee Hwa Yang]

Hi Mike,

The current solution would be to modify read.marrayRaw and read in the two
columns you are interested in.  Construct a filter functions and store the
results in the slot "maW".  

Alternately, you can store any statistics in the class "marrayTwo". See
help(marrayTwo) and then construct a filter functions and store the
results back in maW(marrayRaw).

Hope this helps.

Cheers

Jean
