In your TeX distribution, the documentation of the class is classified with the documentation of the package cjs-rcs-article. The simplest means to open the English documentation cjs-rcs-article.pdf is through the texdoc utility. From the command line:

texdoc cjs-rcs-article

Most specialized LaTeX editors offer an interface to texdoc. To name a few:

• GNU Emacs: C-c ? or M-x TeX-documentation-texdoc;
• TeXShop: Help | Show Help of Package...;
• texmaker: Help | TexDoc [selection];
• WinEdt: Help | LaTeX Doc.

The documentation is also available online via the interface offered by texdoc.org.

The documentation of the class cjs-rcs-article also contains the instructions to authors of The Canadian Journal of Statistics.

The class is distributed with templates for articles in English and in French.

Perhaps the simplest way to obtain a copy of the templates is through the direct links provided in the project repository:

• cjs-template.tex for the English template;
• rcs-gabarit.tex for the French template.

If you are using the version of the class included with your TeX distribution, the templates are normally installed with the documentation.

If you opted for a local or manual installation of the class, the templates reside in your project directory.

The class inserts internal and external hyperlinks into the PDF using the package hyperref. To give a more visible “target” for internal links, hyperref provides the command \autoref.

Therefore, label with \label as usual any text element you wish to link to (section, table, figure, theorem, etc.), and then create the reference with \autoref. The command \autoref automatically provides the description label for the reference, and this becomes part of the link. For example:

You may need to use mathematical notation or symbols in section titles (but try to keep this to a minimum). To do this, wrap the notation in \texorpdfstring. This command takes two arguments:

1. the text to appear in the document;
2. the alternative text for the table of contents of the PDF file, where mathematics is not supported.

For example, the title “Approximating β and λ” will be input as:

\section{Approximating \texorpdfstring{$\beta$}{beta} and \texorpdfstring{$\lambda$}{lambda}}

or perhaps, using Unicode characters, as

The error Improper alphabetic constant is caused by a mathematical symbol in a section title; see /faq/how-do-i-include-math-symbols-in-titles/.
