I was a happy ESS and R user to obtain tex and pdf files from Rnw file with sweave and knitr. I have followed the answer given here, everything worked fine but after several updates or maybe new installation I cannot even find the ess-sweave customization group in Emacs. M-x customize-group: ess-sweave is [No match]. I am using GNU Emacs 25.1.1 on Debian 9 (stable).

ESS version is 20190306.2305.

What am I missing to start to use knitr with ESS?

  • The post you linked to described an obsolete version of ESS. I've updated it to reflect the current approach supported by polymode. If you have any trouble, please leave a comment on the other question.

  • @Tyler, thanks for your answer, it works. As my reputation is low I cannot comment on others' posts. As a next question I would like to use natbib as a reference and I have no clue. This question is already asked; tex.stackexchange.com/questions/267564/…
