[Bioc-devel] Recent / forthcoming changes to Biobase

A quick note to alert developers to an eSet change. There is a new
slot featureData, added following discussion at BioC2006. The slot is
an AnnotatedDataFrame, like phenoData, but meant for
experiment-specific data about features (continue using the annotation
slot for efficiently referencing annotations common to several
experiments). Classes derived from eSet likely need "initialize"
methods modified; for an example see "initialize" for ExpressionSet.

Data instances in Biobase (e.g., sample.ExpressionSet) are *not* yet
updated, but will be in the next several days.
