I modified the definition of ob-R-transfer-variable-table-with-header in ob-R.el by changing 'sep' from \"\\t\" to \"\". Now
#+BEGIN_SRC R :results output :exports both :session :var data.table=data :colnames yes names(data.table) head(data.table) #+END_SRC (note the addition of :colnames=yes) give me: #+RESULTS: : [1] "A" "B" "C" : A B C : 1 115 76 60 : 2 124 78 55 : 3 118 73 65 : 4 114 75 61 : 5 108 74 82 as I expect. What is the current procedure to submit a patch? Thanks, Michael
