Hi Martin,

before I can try to help you I've a question. You mentioned the bundle Rdaemon and CMD+T.
If your TextMate window runs in the Rdaemon mode then you can simply press RETURN to execute the current line. Or do you mean the R bundle? Or do you mean running Rdaemon and having a separate "R" window open?
And CMD+T key equivalent is new to me.

If you run a very large script in "R" mode, including the selection of lines of code, and press CMD+R or in Rdaemon mode SHIFT+CMD+R, then the selected text will be passed via STDIN to a script which reads the text line by line. I do not know ad hoc where the maximum size in respect of the underlying BASH/Ruby script is but I've never come across with such an issue. Can you tell us how large in terms of MBytes and lines "rather long script" is? (simply copy your selection to a new file and save it and look in the Finder how large it is)

[I've just run a script with 2500 lines, ok, it took a while, but finished successfully]


Tiny note:
CMD+R in "R" mode executes the selection or if no selection is present the entire document, thus there's no need to "Select All" CMD+A in beforehand.
