M-x org-babel-execute-buffer

 

Thanks - that  seems to be what I am looking for, but after trying it out, I realized the following: for each block, e new R session is opened. 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.

OTOH this may not make it easier to debug, the babel error window
doesn't list line numbers or blocks where the error occurred.

True.

 

Perhaps that should be a feature request to log what src block or org file
line number the errors occurred in.

That would be nice.

I haven't tried tangling yet, is there a good tutorial somewhere?

No idea - sorry. 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. 

Thanks,

Rainer

 

Thanks.
