Hi, Let's say one has just run a command line command that took an hour and produced a huge matrix as an output. However, one forgot to store the output in a variable. Is there a hidden variable somewhere that stores the result, so that one doesn't have to re-run the analysis for an hour? E.g., x <- whatever_the_last_output_was Thanks!

Or put this inside your Rprofile:
makeActiveBinding("prev", function(...) .Last.value, .GlobalEnv)
I like this 'cause I don't need to include the "()" for prev
to work
properly.
