As far as I can tell S2000 is a Honda sports car. This is *R*-devel, and in R typing x does not call print.default, let alone print.matrix. Can you please check your facts a little?
The models that R considers are S-PLUS 3.4, and these days more often 6.1 as R adopts ideas from S4. S-PLUS 2000 (I guess you meant) is not very like either of those.
