That's perfect! Thanks!

I now see that .Last.value is mentioned in the 'Introduction to R', footnote 5. Sorry, I hadn't read it that carefully.

(Before posting, I even did read
> help('.Last')

but thought that that function wasn't what I wanted. I guess I wasn't using the right keywords.

returns .Last.value as the top hit.

(I also apologize for the long disclaimer at the end. It's automatically generated.)

Something like .Last.value:

  > x=sqrt(2)
  > .Last.value
  [1] 1.414214

which might get more usage if it was less fiddly to type.
