package subcaption - environment subfigure

[GoogleCodeExporter]

Tufte is incompatible with the package subcaption (Tufte: SVN, LaTeX: latest 
MacTex based on LiveTex). Consider the example above:

begin{figure}
  \begin{subfigure}[b]{0.3\textwidth}
    \centering
    \begin{tikzpicture}
      \draw circle (1.25cm) {};
    \end{tikzpicture}%
    \caption{subcaption}
    \label{fig:circle}
  \end{subfigure}%
\caption{main caption}\label{fig:main}
\end{figure}


Then \ref{fig:circle} does not work (Only (??) is shown), but  \ref{fig:main} 
does.

The problem is with the redefinition of the \label command inside tufte floats. This also affects line references with the listings package, see this Stackoverflow post. A workaround is to pretend that the subfigure package has been loaded by setting the Boolean accordingly in your document preamble:

\makeatletter
\setboolean{@tufte@packages@subfigure}{true}
\makeatother
