Graphics, Figures & Tables ⇒ Why can't I use \begin{figure}?

[subjugater]

Code: Select all

\documentclass[a4paper,12pt]{letter}
\usepackage{fullpage}
\usepackage{latexsym,amsmath,amssymb}    % need for subequations
\usepackage{graphicx}   % need for figures
\begin{document}
......
\begin{figure}
\includegraphics[totalheight=0.8\textheight,viewport=50 300 1000 1200,clip]{shear.pdf}
\caption{\emph{caption here}}
\end{figure}
......
\end{document}

When compiling the above script, I was bounced back by the following error message:

Code: Select all

./research.tex:207:Environment figure undefined. \begin{figure}
./research.tex:210:\caption outside float. \caption
./research.tex:212:\begin{document} ended by \end{figure}. \end{figure}

Why can't I use \begin{figure}here? BTW, I use kile in Ubuntu.

Seems to be an incompatibility with the letter document class. It works if you change it to article. I'm not sure if there's a way around it, if you're set on using the letter class.

Thanks, man. You answer is almost what I have thought. It seems that there isn't a way to get around this other than change [letter] to [article].

The figure environment simply isn't defined in the letter class just because float environments don't make sense in a letter.

You can load the caption package and use its \captionof command to get what you want. However, this will look very strange in a letter.

Here is how I solved the problem:

- include the \usepackage{graphicx}

then:

Code: Select all

\begin{minipage}{\textwidth}
\centering
\includegraphics[width=0.50\textwidth]{ResponsiveMutantsMeeples.png}\\
Figure 1. Glycoproteostasis modulation therapy for responsive mutation carriers.
\end{minipage}
