well, this kind of feature isn't implemented. Here arises one question: How do you define the "previous code block"? In terms of lines, or of the begin- and end-characters?

I do not know RStudio very well but maybe I can figure out how it defines it.

On the other hand, did you try the Rdaemon, which means to run R within a normal TextMate editor window (with ALL the TM features)? I find this way to work with R very powerful. Ok, firstly you will be a bit confused that this kind of a R-console is "non-linear in time" meaning you can go up lines, edit stuff and re-run code from there, but it turned out (also on basis of many users) that the Rdaemon opens unforeseen possibilities.

If not, simply set a TM window to R Console (Rdaemon), read the Help, and then type into an empty line "start" and press TAB. 

Cheers,
Hans
