No `ess-noweb-mode`

[iagogv3]

Hi!

I read in the ESS documentation that

ESS provides support for writing and processing Sweave (https://leisch.userweb.mwn.de/Sweave/), building up on Emacs’ ess-noweb-mode for literate programming. When working on an Sweave document, the following key bindings are available:

and then

M-n s Run Sweave on the current .Rnw file. If choose is non-‘nil’, offer a menu of available weavers.

After trying the last without success, and M-x ess-swv-weave, finding that command does not appear among ess command, I also tried M-x ess-noweb-mode, also not finding that command. Why this may be happening?

GNU Emacs 29.4 (build 2, x86_64-w64-mingw32) of 2024-07-05
on Windows 11.

I have found #894, and I wanted to add that I have also tried polymode with poly-R, but M-n w (polymode-weave) returns

weaving latex with command:

     R CMD Sweave escalas.Rnw --options="output='escalas-woven.tex'"

'R' is not recognized as an internal or external command,
operable program or batch file.

(while I can run R with ESS through M-x R)
