[BioC] assigning intensity values

[James MacDonald]

No trick; just use the same pm() accessor function.

new.pm <- <some vector or matrix of numbers>
pm(affybatch.example)[index,] <- new.pm

HTH,

Jim

Hi,
I know that I can extract intensity values using the expression
PM <- pm(affybatch.example)[Index,];
Is there any trick to reassigning new intensity values to the
CEL file?
Thanks for your help,
Lana
