This does not work for literate programming, as different blocks belong to each other, i.e. one block opens a function, the next one closes it. In addition, I want to evaluate the results, i.e. created objects, in R - therefore the session should stay open. So my guess: tangle and debug.

But it works really nice, If each block (in the tangled file) would have a commented header specifying the line number of the org-mode file where the block is located.
