[BioC] sva remove batch effect.

[Fabrice Tourre]

Dear list,

Now I am using sva to remove batch effect in my mircoarray data. First
I used combat to remove know batch effects. The combat can output a
new expression matrix without batch effect, then I used sva to remove
unknow batch effect, but it seems that sva can not output a new
expression matrix. sva take the surrogate variables into the test. How
can I let sva output a new matrix without batch effects?

Thank you
