roman numerals for chapter numbers?

Hi,

I don't think that's possible after reading a related topic here

Prefix section headings with a letter

I want to add a letter prefix to my section (and subsection) numbers, so that 101, 101.1, 101.1.1 become S101, S101.1, S101.1.1 but I'm not sure how to implement. Document headers reproduced below. I just use the #section# , ##subsection## and ###subsubsection### tags. documentclass: article output: pdf_document: number_sections: yes toc: no toc_depth: '1' word_document: toc: no toc_depth: '1' html_document: df_print: paged number_sections: yes toc: no toc_depth: '1' pandoc_args: - --number-sections - --number-offset=300

Roman numerals would not be able to cope with subsections, as you can't write something like 1.2.1 as roman numeral. Also, more theoretically, roman numerals only go up till about 4000, so you can't convert large numbers (though this would not be an issue in a book, as there are likely not that many chapters).

It seems the only solution is to build custom css, js or latex depending on the knitting, but that's too advanced for me Maybe someone else knows how to do that.
