.Last.value or % or ANS or ... (was unix)

 That's true, but I was looking for a more comprehensive solution (which
would be harder to implement, and have the potential to gobble memory like
crazy) of being able to retrieve an list of past values -- "oh, that
third-to-last answer is the one I needed, I'll take that and put it in
this expression"
 (Besides which, 4 characters are better than 11 but worse than 1 or 2)

 I've moved this to R-devel.

abc(<k-th last command line>)

Would be nice to have something simpler than .Last.value

Perhaps I am stating the obvious or being extremely stupid but you can
create a function:

        lv <- function()
         {
         .Last.value
         }

And then use lv() whenever you need .Last.value.

Admittedly, this is NOT the same as having a stack of objects...

It would be no big deal to create a stack of objects resulting from
the last N expressions. What I'm not too sure about is whether you'd
really want that. Notice that it could imply keeping several copies of
a data set in memory. E.g. the value of an assignment like "data <-
transform(data, logx=log(x))" is the value of the RHS.
