I have been using LaTeX for years, but today on sigchi template I am getting undefined control sequence error. I want to place my figures spanning two columns or even in a single column, but none works. Here is a minimal example code:


% Remove or comment out these two lines for final version
\toappearbox{\Large Submitted to CHI'13. \\Do not cite, do not circulate.}
\pagenumbering{arabic}% Arabic page numbers for submission. 

% Use \toappear{...} to override the default ACM copyright statement (e.g. for preprints).

% Load basic packages
\usepackage{balance}  % to better equalize the last page
\usepackage{graphicx} % for EPS, load graphicx instead
\usepackage{times}    % comment if you want LaTeX's default font
\usepackage{url}      % llt: nicely formatted URLs


% llt: Define a global style for URLs, rather that the default one

% To make various LaTeX processors do the right thing with page size.

% Make sure hyperref comes last of your loaded packages, 
% to give it a fighting chance of not being over-written, 
% since its job is to redefine many LaTeX commands.
pdftitle={SIGCHI Conference Proceedings Format},
pdfkeywords={SIGCHI, proceedings, archival format},

% create a shortcut to typeset table headings

% End of preamble. Here it comes the document.

I found a solution. Might be helpful for other people as well: \begin{figure} \centering \subfloat[]{\includegraphics[width=3.1in]{figures/gpEcUND.eps}} \subfloat[]{\includegraphics[width=3.1in]{figures/gpgTND.eps}} \caption{Potential for 0.5 V bias.} \label{fig:EcUND} \end{figure} – mehwish nasim Sep 15 '12 at 13:53
Welcome to TeX.SE! It's great that you found a solution :) Please consider either posting it as a self-contained answer, or deleting your question; it helps to keep the site tidy :) – cmhughes Sep 15 '12 at 15:27
You're loading the subfig package, which provides \subfloat; the \subfigure command was provided by the obsolete predecessor package subfigure. It's better to stick with the newer one. – egreg Sep 15 '12 at 19:28
I will post it as an answer once I get past the 8hrs new user limit. thanks. – mehwish nasim Sep 15 '12 at 20:38

The subfig package requires the usage of \subfloat, rather than \subfigure:

\caption{Potential for 0.5 V bias.}
