R help - Sep 2011 - converting object elements to variable names and making subsequent assignments thereto

This has got to be incredibly simple but I nevertheless can't figure it out
as I am apparently brain dead.

I just want to convert the elements of a character vector to variable names,
so as to then assign formulas to them, e.g:
z = c("model1","model2"); I want to assign formulas, such as
lm(y~x[,1]) and
lm(y~x[,2]), to the variables "model1" and "model2".

There are of course, many more than 2 models involved, so brute force is the
option of absolute last resort.
Thanks for any help.

The usual response to this sort of question is usually something like the
following:

assign() will do what you want; get() runs the other direction. But the more
R way to do it is to put all the models in a list.

It's not clear to me what you're trying to do.

You say you want to assign formulae, such as lm(y~x[,1]) and lm(y~x[,2]), 
to the variables "model1" and "model2".  Do you mean that
you want the
resulting formulae to be lm(y~model1) and lm(y~model2)?

Could you give a more complete example of what you have and what you'd 
like to end up with?
