[BioC] limma - How to write the output of normalizeWithinArray() function output

[Srinivas Iyyer]

Dear group,
I am confused about writing back the MA values from
normalizeWithinArrays() function output.  

Example:

myMA <-
normalizeWithinArrays(my_int_object,method='printtiploess',bc.method='none')


now I want to write the MA values from 30 chips in
myMA to a file or files. 

Is there a way to do that. Would any one please help
me. 
Thanks
Sri
