Hello,

looking deeper into the docs I saw that we could modify the
org-html-mathjax-template in the following way to add the macro.


(setq (org-html-mathjax-template
   "<script type=\"text/x-mathjax-config\">
    MathJax.Hub.Config({
        displayAlign: \"%ALIGN\",
        displayIndent: \"%INDENT\",

        \"HTML-CSS\": { scale: %SCALE,
                        linebreaks: { automatic: \"%LINEBREAKS\" },
                        webFont: \"%FONT\"
                       },
        SVG: {scale: %SCALE,
              linebreaks: { automatic: \"%LINEBREAKS\" },
              font: \"%FONT\"},
        NativeMML: {scale: %SCALE},
        TeX: { equationNumbers: {autoNumber: \"%AUTONUMBER\"},
               MultLineWidth: \"%MULTLINEWIDTH\",
               TagSide: \"%TAGSIDE\",
               TagIndent: \"%TAGINDENT\",
     Macros: {
      R: '{\\\\mathbb{R}}',
      arr: '{#1_{^{}_{#3}}^{^{#2}}}',
      myperm: '{\\\\frac{#2!}{(#2-#1)!}}'
    }

             }
});
</script>
<script type=\"text/javascript\"
        src=\"%PATH\"></script>"))

another quick option is just to define the latex macro directly in the
main body as follows before exporting to html but this would generate an
<error LaTeX Error: Command \R already defined> when exporting to latex

$\newcommand{\R}{\mathbb{R}}$


Hope it helps,

Jeremie
