I am trying to help even though I know little: I used the approach in https://plantarum.ca/2021/10/03/emacs-tutorial-rmarkdown/ > The main function you need for this is polymode-export, bound to M-n > e. > > The first time you run this, you’ll be asked which exporter you would > like to use. There are two choices, markdown and markdown-ess.
So, if you choose markdown it will ask for format and then you can type pdf or html, it will weave and then look for pandoc. I have this in my .emacs '(markdown-command (concat "pandoc" " --from=markdown --to=html" " --standalone -- mathjax --highlight-style=pygments")) You can see that it ignores the to=html and asks me every time. It also igonres the title section, where I specify the output format. So, it looks like polymode does not know how to read the title/yaml, but that is not a big deal as you can set that in the dialog after M-n e Cheers Stephen On Wed, 2022-09-07 at 17:03 -0400, Vincent Goulet via ESS-help wrote: > Hi all, > > A large part of my work in Emacs involves editing Sweave (.Rnw) > files.
