I'm pretty sure it was Tal's request, the responses and his posting of that link on Rhelp that I was remembering. 

There is also the possibility of accessing the "system variable": .Last.value

You cannot use it with sink("file.txt") since that command returns NULL and removes the temporarily saved value you might want to put in a file, but you can use `capture.output` which I see was recently given a 'split' option. I found this in the NEWS file which on my machine is at http://127.0.0.1:21567/doc/html/NEWS.html, but on your machine may have a different access method.

capture.output(.Last.value, file="save.txt")

Should place a text copy of the screen output resulting from the last console command into a file.

Best;
David.
