Hmm, the main issue here is that the output of the R session is not
bound to any specific TM window ('only' to the current one). This is
an advantage, I can run R code also from other docs like from a TeX
file; but has also its disadvantages.
If I would bind the output of the R session to one window then one
would have the problem how to update/reach that window (it would be
possible but ...)
I'm using very often your mentioned workaround, two windows, for
developing a function for instance. Then I send the function to the
Rdaemon, switch to the Rdaemon window, and try it out. If an error
occurred in that code sent a new window would be opened mentioning the
On the other hand one should ask why one needs the behaviour you
mentioned. One can do this also in a doc associated to Rdaemon.
Remember the Rdaemon doc is NOT a time-linear console, it's still an
editor window, thus you can run code, go some lines back, run an other
command, press ⌘Z for undo, correct the command, delete unused stuff,
In other words why are you using two windows?
See: http://www.bibiko.de/TM_R_ex01.mov as naïve example.
OK. This workaround is totally different from the 'normal' R console,
but since I'm using it all the time I have really problems to use
R.app or the Terminal because I miss this flexibility.
Nevertheless I'll try to find a workaround similar to that one you
