At the moment, ob-R.el does not support :colnames to have a list of column names as an argument. This seems to have been raised on the list many years ago [1], but it does not look like it was implemented. Is there a possibility that this could be implemented?
Also, is it possible to allow :hlines to have a list of row numbers as arguments after which horizontal lines are drawn in the results? Could we support a syntax such as the following
:hlines '(2 5 8)
Or something of this kind, which could then be used to draw lines after these row numbers?
I think these two features would make it much easier to customise tables created using R code blocks.
Would appreciate any comments and suggests.
Thanks very much and best wishes,
