LyX ⇒ Problem with cross-reference and label

[lyxrocks]

I am using this template to write a math paper.

I cannot get it to reference to a lemma, I want it to say "according to lemma 1" but it says "according to [1]" treating my labeled lemma as a labeled equation.

I don't know anything about LyX but this is standard LaTeX behaviour: the \ref command (which surely is used) only prints the number of the referenced label. So you have to add the type yourself (Lemma~\ref{<whatever label has been used>}).

Code: Select all

\documentclass{elsarticle}

\newtheorem{lem}{Lemma}
\newproof{pf}{Proof}

\begin{document}

\begin{lem}\label{lem:aaa}
 aaa
\end{lem}
\begin{pf}
 aaa
\end{pf}

\begin{lem}
 bbb
\end{lem}
\begin{pf}
 According to Lemma~\ref{lem:aaa}
\end{pf}

\end{document}

There are packages like cleveref or varioref which provide means to add the name automatically. I would think there should be a way to use them with LyX as well:

Code: Select all

\documentclass{elsarticle}

\newtheorem{lem}{Lemma}
\newproof{pf}{Proof}

\usepackage{cleveref}
\crefname{lem}{Lemma}{Lemmata}
\begin{document}

\begin{lem}\label{lem:aaa}
 aaa
\end{lem}
\begin{pf}
 aaa
\end{pf}

\begin{lem}
 bbb
\end{lem}
\begin{pf}
 According to \cref{lem:aaa}
\end{pf}

\end{document}
