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.
