Hi, This is a problem about writing R documentation (R-exts 2.6). The command "\deqn" defined in "Rd.sty" is:
\newcommand{\deqn}[2]{\[#1\]} which will put mathematical formulae in the "displaymath" environment; 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.
