[BioC] Illumina Expression analysis from iDAT files

[Gordon K Smyth]

Dear Sean and Mike,

We (actually Matt Ritchie) have written a nice little function that uses 
readIDAT() to read the IDAT files and assembles the pieces into a data 
object ready for limma analysis.  The output is an EList object, but it 
could be an ExpressionSet instead.

It has been suggested that this function could be added to the limma 
package, but I wondered whether the illuminaio package would be the best 
home.

What would you like us to do?

Best wishes
Gordon
