[R] Error with 'var' in JGR

[Bret Collier]

R-Users,
I had a strange occurrence this AM I could use some help with.  'var' seems to have ceased to work for me when I used JGR 1.3 interface.  So, I ran a quick test (following pg 57 of Dalgaard) in both the basic RGui and JGR interface (see below).   I have re-installed R 2.2.1 and JGR 1.3 but had no luck so far figuring this out?  Anyone have a suggestion? Or did I just make a mistake somewhere (which is more than likely).

Thanks,
Bret
