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

Tyler, thanks for your response. I had found your website while 
searching for a solution to my problem.

Currently, I have this in my .emacs.d/init.el file:
(setq load-path (append '("~/.emacs.d/polymode/" 
"~/.emacs.d/polymode/modes") load-path))
(require 'poly-R)
(require 'poly-markdown)
(add-to-list 'auto-mode-alist '("\\.Rmd" . poly-markdown+r-mode))

This has been working for me without error so far.

I commented out the last line and added this one:
(add-to-list 'auto-mode-alist
               '("\\.[rR]md\\'" . poly-gfm+r-mode))

When I save my init.el file and restart Emacs with a .Rmd file, I get 
this error message:

File mode specification error: (void-function poly-gfm+r-mode)
Package cl is deprecated

I'm using GNU Emacs 27.1, with rmarkdown 2.21. I'm not able to install 
or find a poly-R or polymode package for this version of R

Any ideas what I'm doing wrong? Thanks for any help and guidance.

-Kevin
