Hello, It seems that using ":var d=data" breaks ":colnames yes" in the header of an R code block. In the example below the first code block uses ":colnames yes" and gives the correct output, the second code block uses ":var d=data" to read the data in the table (although it read the header as data), and the third code uses both ":colnames yes" and ":var d=data" but gives the error "Wrong type argument: sequencep, hline". Thanks, Paul # ================= Start example ===================== #+name: data |--------+--------| | x | y | |--------+--------| | 111.89 | 88.37 | | 392.12 | 297.33 | |--------+--------| This code block works as expected. #+begin_src R --no-save --no-restore :colnames yes data.frame(x=1, y=2) #+end_src #+RESULTS: | x | y | |---+---| | 1 | 2 | This code block shows that the data in the table can be read (although the table header is read as data). #+begin_src R --no-save --no-restore :var d=data d #+end_src #+RESULTS: | x | y | | 111.89 | 88.37 | | 392.12 | 297.33 | However, using both ":colnames yes" and ":var d=data" together gives an error "Wrong type argument: sequencep, hline" #+begin_src R --no-save --no-restore :colnames yes :var d=data data.frame(x=1, y=2) #+end_src #
