[BioC] xps: convert a data frame to ExprTreeSet

Dear Steve,

There exists a function 'root.expr()' to create a new ExprTreeSet for an 
existing root expression file.

You can look at the source code 'root.expr.R' how to create an 
ExprTreeSet which takes a data.frame as slot 'data'.  However, I am not 
sure if this will help you.

I would need more information what you want to do.

Best regards
