[Tex/LaTex] Referencing an Appendix while using PRL style

appendicesrevtex

I'm writing a file with two appendices but found that \ref{} isn't working; that is, Appendix~\ref{AppendixLabel} isn't outputting Appendix A – just Appendix. I soon figured out that this is because using \documentclass[aps,prl...]{revtex4-1} disables section numbering, which removes the 'A' from Appendix A. Changing prl to prx fixes the issue, but I believe the citation style is different for prx, so I'd like to avoid this. Is there any way to get references for the Appendices while still using PRL style?

Here's a minimal example of code that doesn't give the Appendix a label:

\documentclass[aps,prl,twocolumn]{revtex4-1}
\begin{document}
Appendix~\ref{A1}
\appendix
\section{Appendix 1}
\label{A1}
Hello
\end{document}

Best Answer

The prl option sets

 \c@secnumdepth=-\maxdimen

so sections are not numbered, as such there is no number to reference, You could undo this with

\setcounter{secnumdepth}{2}

But beware that the whole point of a journal class like revtex is to remove such choices from the author and enforce a publisher style.

If you want to suppress the cross-reference name for a particular type, it's simpler to just use

\crefname{appendix}{}{}

Then all the formats get defined for you automatically, instead of having to redefine \crefformat, \crefmultiformat, \crefrangeformat, and \labelcrefformat separately. (These days, cleveref is clever enough to omit the usual non-breaking space after the cross-reference name if you define an empty name.)

However, this solution (and ach's too) will break cleveref's multi-reference features somewhat. E.g. \cref{apdx1,apdx2,apdx3,apdx5,apdx7} will produce "Appendix 1 to Appendix 3 and Appendix 4 and Appendix 5", instead of "Appendices 1 to 3, 4 and 5".

Luckily, elsarticle defines an \appendixname macro to hold the string used in appendix labels, no doubt to allow it to be customised easily. So the best solution is simply to get rid of elsarticle's \appendixname entirely, and let cleveref do its job as usual, by adding this to your preamble:

\def\appendixname{}

Use this solution. Add the package tocloft and after appendices environment do \addtocontents{toc}{\cftpagenumbersoff{section}}

Your code will be reworked as

\documentclass{article}
\usepackage[title,titletoc]{appendix}
\usepackage{tocloft}
\usepackage{lipsum}

\begin{document}

  \tableofcontents
  \clearpage
  \section{first}
  \section{second}
  \pagebreak
  \begin{appendices}
    \addtocontents{toc}{\cftpagenumbersoff{section}}
    \section{additional material}
    \setcounter{page}{1}
    \renewcommand{\thepage}{\thesection -\arabic{page}}

    \lipsum

    \pagebreak
    \section{more of it}
    \setcounter{page}{1}
    \renewcommand{\thepage}{\thesection -\arabic{page}}

    \lipsum

  \end{appendices}
\end{document}
