Yes, you just show that the documentation is not up-to-date, as that functionality *is* implemented for most languages. Doing some bit of archeology, I just found out that: - Eric wrote a patch to support the above (but it hasn't be applied), - I (!) even wrote a test of that functionality (for a shell block) in `testing/lisp/test-ob.el'. See https://lists.gnu.org/archive/html/emacs-orgmode/2013-04/msg00527.html: ┌──── │ It looks like ob-R implements its own result table reconstruction │ instead of using the general support. This is because R actually │ has a notion of column names and row names internally. The │ implementation in ob-R does not correctly handle specified colnames │ as your example shows. │ │ The attached patch brings ob-R closer to the using the unified │ general table reconstructed used in most other languages, and fixes │ your problem mentioned above. I haven't applied it however, as it │ may introduce other bugs related to specifying column names from │ within R. For example, I'm not sure that it will now correctly │ apply column names from a table built entirely from within R. │ │ Additional testing by someone more familiar with R than myself would │ be greatly appreciated. └──── Should such someone (more familiar with R) be able to confirm that his patch work without introducing problems, it could be applied so that R should behave the same as in most languages...
