Thanks Arash,
Yes I know about that trick but o am wondering whether something else can be 
done.

Thanks

IIRC that one is built in and cannot be turned off (I think this is
also documented somewhere in the manual but I didn't check).  Therefore
you have to go through some more troubles (see Tassilo's message).

The usual trick to fix this is to write something like this:

  the average salary is $\bar x=\Rexpr{mean(mydata$salary}}$% $

You get misformed fontification, but you can limit it until EOL.

Hello Tassilo,


Thanks for this but it does not work for me. I also worked on the code 
yesterday (for polymode) so the $ sign inside a R code chunks is not the 
problem. The problem is having the code chunk inside the $ signs.  as this 
image shows. You see that the first \Rexpr is not a problem but the second one 
is. The init.el file is very simple just defining these code chunks and loading 
ess and auctex ( I can send it if need be). I tried it with your code and 
without, I had the same outcome.

[image to show fontificxation where when Rexpr is whithin $ signs it 
bleeds out]

Hi Jean,



Anyway to turn off the fontification of math within $ signs? I know I

like to  turn it right off.


There is no simple option for it but this seems to work:

--8<---cut here---start->8---
(defun my/font-latex-disable-dollar-math ()
  (cl-flet ((f (lst)
  (seq-filter (lambda (e)
(not (eq (car e) #'font-latex-match-dollar-math)))
  lst)))
(setq font-latex-keywords-1 (funcall #'f font-latex-keywords-1))
(setq font-latex-keywords-2 (funcall #'f font-latex-keywords-2

(advice-add
 #'font-latex-make-user-keywords
 :after
 #'my/font-latex-disable-dollar-math)
--8<---cut here---end--->8---

Note however, that this will also disable $$...$$.  And since
super/subscript fontification is only performed in regions which are
already identified to be math, that's also disabled.

Bye,
Tassilo
