Hi!

Concerning different behaviour between 1.9.1 patched and: R : Copyright 2004, The R Foundation for Statistical Computing Version 2.0.0 Under development (unstable) (2004-09-06), ISBN 3-900051-07-0

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

The same code:

as(mvl[[1]],"vector")
causes under R1.9.1 to enter the function setAs("Massvector","vector"

      ,function(from)
...

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

as(as(mvl[[1]],"Matrix"),"vector")

and its not what I would expect.

Is this an intended behaviour in R2.0.0?

/E
