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

Hi Kevin,

If you have an older version of `poly-R`, the function `poly-gfm+r-mode` might not be present. This was added to `poly-R` dev in July 2021, I'm not sure exactly when it would have been added to the released version.

If that's the case, updating to the current version of `poly-R` should fix the problem.

Alternatively, you need the following code evaluated *after* `(require 'poly-R)` and *before* `(add-to-list ...)`:

```
(define-polymode poly-gfm+r-mode poly-markdown+r-mode 
  :lighter " PM-Rmd(gfm)"
  :hostmode 'poly-gfm-hostmode)
```

But that really shouldn't be necessary.

Best,

Tyler
