Line breaks in mathematical formulae in Rd files (PR#13287)
...ent; that means line breaks are not allowed (or will not be shown) in formulae, but sometimes we do need multiple lines of formulae. One solution is to write several equations using "\deqn", but I think to change the definition of "\deqn" is better: \newcommand{\deqn}[2]{\begin{eqnarray*}#1\end{eqnarray*}} This will not change the pdfLaTeX output effect, moreover, line breaks and alignments using "&" will be available in math formulae.

Line breaks in mathematical formulae in Rd files
Hello, I would like to implement the feature request described here: https://bugs.r-project.org/bugzilla3/show_bug.cgi?id=13287. I think this is a very worthwhile feature. However, I need just a little push in the right direction. When I added either a new command or change the old one to use eqnarray as proposed, the "\\" newline characters were not properly passed to latex - even when I escaped them both with something like "\\\\". What is happening behind the scenes that I am not understanding that is disallowing me from making this small change so I can use "\\&quot...
