[R] Equivalent to Matlab's "Ans"

Hi everyone, I was just wondering if there is an equivalent in R to the shortcut "Ans" in MatLab whereby I can use the previous result for the current command? This could save a lot of time when hacking in R itself, not from an editor. Thanks, Stephane [[alternative HTML versi
