beamer

I'm creating a Beamer presentation that has a lot of example LaTeX in it, which has to go in a verbatim environment. I'm getting tired of typing \begin{example} \begin{verbatim} Verbatim Text \end{verbatim} \end{example} I wish to create a new command or environment that will shorthand this for me. I also need this for blocks and theorems, since I'm using those frequently as well. But if I can figure it out for examples, it should be easy to translate to another example. I can't create a new environment or command using just \begin{verbatim}, since it cuts off the rest of the command. So I

Hi I was wondering how to resize matrices in a beamer environment. Currently I am writing the following code: \begin{align*} \left( \begin{array}{ccccccc} 0 & 1 & & & & & \\ -1 & 0 & & & & & \\ & & 0 & 1 & & & \\ & & -1 & 0 & & & \\ & & & & \ddots & & \\ & & & & & 0 & 1 \\ & & & & & -1 & 0 \end{array} \right) \end{align*} and the matrix takes up almost a whole page. I would like it to be about half a page in height. Benjamin Bannier See this answer for how to change font dimensions in LaTeX's math mode.

All the themes available with Beamer are described in the user guide ; just pick one that suits your

When I include \usepackage{Sweave} in the preamble of a beamer presentation, beamer ignores changes to font, e.g., \usepackage{helvet} . Here is a minimal example: \documentclass[professionalfonts]{beamer} \usepackage[T1]{fontenc} \usepackage{helvet} \usepackage{Sweave} \begin{document} \begin{frame} Lorem ipsum dolor sit amet, consectetur adipisicing elit, sed do eiusmod tempor incididunt ut labore et dolore magna aliqua. Ut enim ad minim veniam, quis nostrud exercitation ullamco laboris nisi ut aliquip ex ea commodo consequat. \end{frame} \end{document} The text is set in computer modern,
