Comment:
Dear Volker,
1. Great idea ! I am sure a lot of use cases exist in the Sagemath
ecosystem.
2. Your ticket (tested against a fresh clone of 6.10rc0) :
* builds, and
* passes ptestlong.
* Installing r_jupyter effectively installs an R kernel in Sagemath's
Jupyter notebook.
* This notebook is functional (i. e. one can create a worksheet whose
native language is R).
3. However, over Sage 6.10rcO, the Rpy2 interface cannot be used in a
Sagemath notebook :
* The "%load_ext rpy2.ipython" command is not recognized
* The "%load_ext rmagic" command is recognized (with a warning), but :
* The %R (and %%R) commands are not recognized
You can compare these results (illustrated in "Untitled3-native.pdf") with
those obtained on 6.10rc0+Trac#19638+manual installation of IRKernel in R,
which also illustrates the problems with this current implementation :
* uses a different instance of R than the Sage's pexpect interface
* converts the output in strange formats, different from those used by
Sages's pexpect interface.
If your goal was strictly limited to providing an R notebook in Sage's
Jupyter, I think it's good to go. If you aimed at providing Sage with an
alternative interface to R, it needs work (needs
[http://trac.sagemath.org/ticket/19638 Trac#19638], IMHO, but I'm
biased...).
I would be interested in your point of view in the question I posed in
sage-devel. William's sarcastic non-answer misses a part of the point.
Sincerely yours,
