hi all,

I am Ganiraju, a new member of the group. (and currently using the affy
package)

I m trying to use "loess" method in expresso function to normalize the data.

While running Im getting an error: "non-numeric matrix extent"

I didnt really understand whether is some problem with ReadAffy(), or
functinoality of "loess", whether it can be used on all kinds of data or
not.

Also, Im runnig sort of memory. Is there any other way to create virtual
memory other than using "memory.limit."

Thanks in advance,
Ganiraju
