[BioC] ExpressionSet Object

[Valerie Obenchain]

Hello,

Please post questions to the Bioconductor mailing list

     http://bioconductor.org/help/mailing-list/

By doing this others can learn from the exchange and a larger pool of 
experienced users has the opportunity to respond. I've cc'd the list on 
this email. When you respond, please respond to all so the list is copied.

As for the question, I need a reproducible example. I don't know what 
your data look like or what error messages you are seeing. Please 
provide an example and the output of typing sessionInfo() so I can see 
what package versions you are using.

Valerie
