Version 2.0.0 Under development (unstable) (2004-09-06), ISBN 3-900051-07-0

as(x,"vector"); x is of class "Massvector"; never enters setAs("Massvector","vector"...

The same code:

causes under R1.9.1 to enter the function

This never happens under R2.0.0.

The class "Massvector" contains class "Matrix"

A phenomenological description of what happens instead with R2.0.0 is

Is this an intended behaviour in R2.0.0?
