[R] using index of a loop as a macro variable

I'm a long-time STATA user and a R newbie. I'm doing ok, but I'm addicted
to STATA macro variables.  Is there something like a macro variable in R?

Specifically, I'd like to be able to do something like

for (i in 1:3) {
	x`i' <- ...

where R would resolve x`i' to the objects named x1, x2 and x3 as I move
through the loop.  I guess I could create these in advance of the loop and
fill them in, but I'd rather not.  

Is there a way to use an index of a loop in this manner?
