[Bioc-devel] Interoperability between DataFrame and dplyr?

Seems to me that DataFrame is too flexible -- you can have very complex
objects in the columns (anything that inherits from Vector) with which, in
its current state, dplyr would not work too naturally.  You would wind up
doing a fair amount of coercion of such entities, so it seems to me that
arranging a coercion of DataFrames satisfying specific conditions to
data.frame would be a path of low resistance.

Ready to be corrected of course.
