variable call problem in asreml-R

Hi all,

I have a list of explanatory variables that I'd like to use them one by
one as fixed in a mixed model. Instead of typing each one's name when
it's called, I'd like to use something like data.frame.name[[i]] for the
ith column, which works OK with lm(). But with ASReml-R, I got:

Error in '[.data.frame'(data.frame, , v) : undefined columns selected.

Any suggestion appreciated.

Regards,

Xianming
