# HELP Lyx command \appendix

for my thesis i decided to improve my work inserting directly in Lyx the command "\appendix" but i don't understand how to end this part. I would like to insert an Appendix between two different chapters but if i use this command everything i'll write after that will be inside the Appendix without the possibility to come back to a "normal chapter". Could someone help me? Could someone explain me how to end the \appendix part? Thanks a lot!!

You can use the appendix package:

\documentclass{book} % or report or ...
\usepackage{appendix}
\begin{document}
\chapter{First}
text
\begin{subappendices}
\section{An appendix}
text
\section{Another appendix}
text
\end{subappendices}
\chapter{Second}
text
\end{document}


Read the manual (> texdoc appendix) for more information.

• Thanks for your answer, but I get an error message "LaTeX Error: Environment subappendixes undefined." Oct 7 '18 at 20:05
• @TanjaSantner My apologies, I made a typo. It should be \begin{subappendices} and \end{subappendices}. I have corrected my answer. Oct 8 '18 at 18:12

This new command \noappendix should work, at least with a manual set up.

\makeatletter
\newcommand\noappendix{\par
\setcounter{chapter}{2}% <--manually insert the number of chapters before \appendix was used
\setcounter{section}{0}%
\gdef\@chapapp{\chaptername}%
\gdef\thechapter{\@arabic\c@chapter}
}
\makeatother

• Thank you for your answering my question. I tried what you told me to do, but the chapter after my "Appendix" still still appears as an appendix. Oct 7 '18 at 19:59
• Did you put the code on preamble and then \noappendix just before start the new chapter? Oct 8 '18 at 11:34
