Hi,

read.marrayRaw is design to read data from flat file into R.  If you
already have your data in R as an matrix object, what you can do is the
following:

## The following will only read one array into marrayRaw.
array.raw <- new("marrayRaw", maGf=array[,"F1Median"],
maGb=array[,"B1Median"], maRf=array[,"F2Median", maRb=array[,"B2Median"])

Cheers

Jean
