Tyler, thanks again for your help. I'm sorry to burden you with my problems, but I'm stuck again.
I think I have everything installed and up to date. Here's an excerpt from M-x package-list-packages: markdown-mode 20220212.728 installed Major mode for Markdown-formatted text poly-R 20230416.1454 installed Various polymodes for R language poly-markdown 20230202.1210 installed Polymode for markdown-mode poly-noweb 20200316.1315 installed Polymode for noweb polymode 20230317.1218 installed Extensible framework for multiple major modes With the exception of poly-noweb, they're all 2023 packages. Yet, when I open an *.Rmd file, I get this in the Messages buffer: File mode specification error: (error Autoloading file /home/kevin/.emacs.d/polymode/modes/poly-R.el failed to define function poly-gfm+r-mode) Package cl is deprecated I then added your alternative define-polymode section, and the error about poly-gfm+r-mode went away, but I still have this message in the Messages buffer when I start Emacs with an *.Rmd file: File mode specification error: (cl-no-applicable-method clone nil) Package cl is deprecated I can't find a reference to a 'cl' package in my init.el. In addition, the *.Rmd file is in Fundamental mode, and not ESS or poly-R mode. When I try to manually invoke the poly mode, with 'M-x poly-gfm+r-mode', I get the message: cl-no-applicable-method: No applicable method: clone, nil Any ideas what's going on with my system? I'm so worried I'm just making a hash of things with these changes. Thanks for any advice or guidance. -Kevin On 4/22/23 06:00, ess-help-requ...@r-project.org wrote: > ------------------------------ > > Message: 2 > Date: Fri, 21 Apr 2023 11:09:43 -0400 > From: "Tyler Smith"<ty...@plantarum.ca> > To: ESS-help<ess-help@r-project.org> > Subject: Re: [ESS] Emacs, ESS and Rmarkdown: Is this the way compile > is supposed to work? > Message-ID:<a2b88f26-7760-41c2-8e9d-e4ea5de4b...@app.fastmail.com> > Content-Type: text/plain; charset="us-ascii" > > Hi Kevin, > > If you have an older version of `poly-R`, the function `poly-gfm+r-mode` > might not be present.
