"I also don't understand why it would be set to X11 in a plain-old R session"
R is an open source derivative of S and S-PLUS--"S" was the "Statistics Language" MIT X Consortium's "X Motif" is the default output of R from its inception R, S, S-PLUS have always made such output as its default Suggest you just "get with the program"--thousands of R libraries are ready for you to use, extend and create your own libraries if you like--all leveraging the power of X11R6 --i.e. the XWindows system: https://en.wikipedia.org/wiki/X_Window_System By the way Micro$oft Windows is based on MIT's W--W stood for Windows--yet another thing MicroSoft swiped and monopolized and then sued others about whenever possible--rather than join the open source & free software movement X11 is free & open source--all the best software is free & open source--like Emacs Org-Mode On Mon, Apr 6, 2020 at 9:27 PM Matt Price <mopto...@gmail.com> wrote: > > > On Sun, Apr 5, 2020 at 1:19 PM Berry, Charles <ccbe...@health.ucsd.edu> > wrote: > >> >> >> > On Apr 4, 2020, at 4:27 PM, Matt Price <mopto...@gmail.com> wrote: >> > >> > Does anyone know much about the difference between an R session opened >> by typing M-x R, and the R session opened by org-babel? >> >> >> Short answer: almost none. >> >> Long answer: what `org-babel-R-initite-session' and friends do. >> > :-) thanks, I should have been looking for that > >> >> > >> > I'm just learning R and my usual method for learning a language is to >> keep a kind of notebook in org with code snippets they I can execute and >> iterate on rapidly as I learn.
