Just a couple of thoughts on compatibility with S-Plus.
If we are going to do efficient programming in R, it is a one-way
street. For example, for speed, I use the scoping rules of R, meaning
that nothing I write will work in S-Plus. In my opinion, that is the
way it should be or we shall be repeating the Intel/MS-DOS story. It
is useful for the new, more powerful program to be able to use older
code but this should not handicap it or destroy its advantages.
  Hence I am for one-way compatibility that is off by default but can
be turned on if needed. Ross seems to be pointing in the right direction.
PS Can we have some hints as to what will be in this new graphics
library. I trust that Lisp-Stat code is being used to the hilt. I am
dreaming of dynamic 3D graphics, brushing, linking, ...
