Re: st: R: variable not found?

Paul, 



Your use of the -test- statement appears to be incorrect, and unnecessary too.  The output  of -manova- do give the (four) tests that all groups have zero coefficiernts

 You must test four coefficients, not one, if you want a global test of group differences.
I'd also remind the group that the FAQ suggest we don't respond to requests for help with homework.

In my attempt at brevity, I didn't note that the variables are turned
to lowercase when pasted, and we were running the command with the
correct case.  And the error is actually "regressor group not found"
My apologies for the erroneous description.

This seems like a bug.  It's replicated in stata 12.
