[R] RMySQL's column limit

My apologies,

I'm using R v2.2.1 via the JGR Editor GUI, RMySQL v0.5.7 under windows
XP with latest patches.

MySQL is "server version: 4.1.12"
I'm pretty sure it's running on a linux box.

The dimension of template is >2000, I know the error kicks in at 3000,
but haven't iterated to find the exact point - if it would help I can
do this.

Regards
Mark
