[R] creating named elements of lists on the fly

HI Folks,

I'm trying to create a list with named elements. Only, I don't know the names of the elements a priori (they come from the data being calculated). Currently, my approach is to create an environment, then assign things to the environement, then as.list the environment to get a list. 

Running the code gives, for example:
> e2 <- new.env(FALSE, NULL)
> assign("dude", 123, env=e2)
> assign("chick", 456, env=e2)
> as.list(e2)
Error in as.vector(x, "list") : cannot coerce to vector

Is this the best way to make a list like this? 

Thanks,
Ben
