[Tex/LaTex] Label appendix as Appendix I, II, III rather than Appendix A, B and C

appendicesnumberingsectioning

When I am using the \appendix it is automatically naming the Appendix as Appendix A, A.1, A.2 etc.

Is there a way to change it to Appendix I, I.1, I.2, II.1, etc?

here is my current appendix commands:

\appendix
\include{AppendixA}
\cleardoublepage
\include{AppendixB}
\cleardoublepage

Best Answer

This depends on your document class. If it has \chapters, then you can use

\renewcommand{\thechapter}{\Roman{chapter}}

otherwise (if it the highest sectional unit is \section), use

\renewcommand{\thesection}{\Roman{section}}

after \appendix. Combining this into the document preamble (not a bad thing), you could use

\let\oldappendix\appendix
\renewcommand{\appendix}{%
  \oldappendix%
  \renewcommand{\the<unit>}{\Roman{<unit>}}}%

where <unit> defines the highest section unit in your class (say chapter or section).
