[ESS] Fwd: Emacs, ESS and Rmarkdown: Is this the way compile is supposed to work?

Thu Apr 20 19:55:19 CEST 2023

Hi Kevin,

You should be able to do what you want directly from the `.Rmd` buffer. I posted a tutorial here:

https://plantarum.ca/2021/10/03/emacs-tutorial-rmarkdown/

With the right packages installed, from the .Rmd buffer you can export your file with `M-n e`, select `markdown` and `html` when prompted, and the html will be generated and opened in a web browser.

The tutorial walks you through the steps in more detail.

Best,

Tyler
