Description:

     These generic functions access the expression and error
     measurements of assay data stored in an object derived from the
     'eSet-class'.

Usage:

     exprs(object)
     exprs(object) <- value
     se.exprs(object)
     se.exprs(object) <- value

Arguments:

  object: Object derived from class 'eSet'.

   value: Matrix with rows representing features and columns samples.

Value:

     'exprs' returns a (usually large!) matrix of expression values;
     'se.exprs' returns the corresponding matrix of standard errors,
     when available.
