Text Formatting ⇒ Formatting in Beamer

[Suppa808]

Hi, I'm turing a paper I wrote into a beamer presentation and when I copy the code from my paper and put it into beamer it doesn't compile correct and guidance would be great. Thanks.

Here's the code.

Code: Select all

\begin{frame}
\frametitle{Asset Modeling}
\begin{center}
  \begin{tikzpicture}[>=stealth,sloped]
    \matrix (tree) [%
      matrix of nodes,
      minimum size=1 cm,
      column sep=2.5 cm,
      row sep=.25cm,
    ]
    {
          &   & $S(0)(1+a)^2$ \\
          & S(0)(1+a) &   \\
      S(0) &   & S(0)(1+a)(1+b) \\
          & S(0)(1+b) &   \\
          &   & $S(0)(1+b)^2$ \\
    };
    \draw[->] (tree-3-1) -- (tree-2-2) node [midway,above] {$p$};
    \draw[->] (tree-3-1) -- (tree-4-2) node [midway,below] {$(1-p)$};
    \draw[->] (tree-2-2) -- (tree-1-3) node [midway,above] {$p^2$};
    \draw[->] (tree-2-2) -- (tree-3-3) node [midway,below] {$(1-p)p$};
    \draw[->] (tree-4-2) -- (tree-3-3) node [midway,above] {$(1-p)p$};
    \draw[->] (tree-4-2) -- (tree-5-3) node [midway,below] {$(1-p)^2$};
  \end{tikzpicture}
\end{center}
\end{frame}

Hi and welcome,

i am not a TikZ expert, i rarely use it. I think you need to escape the ampersands with back slashes, i.e. \& to make it work since beamer messes with category codes.

I couldn't test it though, because i cannot compile the code snippet. Stuff is needed and i don't know if it is part of some library or stuff defined locally by you. So, best always prepare something others can take and do tests with.

Welcome to the forum!

It doesn't compile because there's no \documentclass command. Something else could be missing. I guess you used it in the original but did not copy here. But this makes testing impossible. A minimal working example though is usually a guarantee for getting a solution. Besides quoting, mentioned by Johannes, I guess you need to define an ampersand replacement using an option in TikZ.
