TikZ animated Equation in Beamer

Question

I'm trying to reproduce the example on creating a Presentation with LaTeX Beamer – Equations and tikz and the given code throws the following error

Package pgfkeys Error: I do not know the key '/tikz/na'.

The LaTex code is

\documentclass[compress]{beamer}
\usetheme{Warsaw}
\usepackage{amsmath}
\usepackage{amssymb}
\usepackage{tikz}
\usetikzlibrary{arrows,shapes}

\tikzstyle{every picture}+=[remember picture]

\begin{document}

\begin{frame}
\frametitle{Test}


\begin{itemize}
\item Overall mean \tikz[na] \node[coordinate] (s1) {};
\end{itemize}

\tikzstyle{na} = [baseline=-.5ex]

\begin{equation}
y_{ijk} = \tikz[baseline]{ \node[fill=blue!20,anchor=base,rounded corners=2pt]
  (d1) {$\mu$}; }
+ \tikz[baseline]{ \node[fill=red!20,anchor=base,rounded corners=2pt]
  (d2) {$r_{i}$}; }
+ \tikz[baseline]{ \node[fill=green!20,anchor=base,rounded corners=2pt]
  (d3) {$c_{j}$}; }
+ \tikz[baseline]{ \node[fill=yellow!20,anchor=base,rounded corners=2pt]
  (d4) {$t_{k}$}; }
+ \epsilon_{ijk}
\end{equation}

\begin{itemize}
\item Effect of row $i$ \tikz[na] \node[coordinate] (s2) {};
\item Effect of column $j$ \tikz[na] \node[coordinate] (s3) {};
\item Effect of treatment $k$ \tikz[na] \node[coordinate] (s4) {};
\end{itemize}

\begin{tikzpicture}[overlay]
\path[->] (s1) edge [bend left] (d1);
\path[->] (s2) edge [bend right] (d2);
\path[->] (s3) edge [out=0, in=-90] (d3);
\path[->] (s4) edge [out=0, in=-90] (d4);
\end{tikzpicture}

\end{frame}

\end{document}

Also my equation is not animated. Any help to fix this error will be highly appreciated. Thanks

If you move the \tikzstyle{na} = [baseline=-.5ex] to be in the preamble, then it compiles:

Notes:

Two compile runs are required, the first to figure out the placement, the second to draw the arrows.
You should be using the \tikzset instead of \tikzstyle as per: Should \tikzset or \tikzstyle be used to define TikZ styles?

Animation:

Since you are using the beamer class, the \pause macro can be used to create the effect of animation across several slides:

\begin{tikzpicture}[overlay]                  \pause
    \path[->] (s1) edge [bend left] (d1);     \pause
    \path[->] (s2) edge [bend right] (d2);    \pause
    \path[->] (s3) edge [out=0, in=-90] (d3); \pause
    \path[->] (s4) edge [out=0, in=-90] (d4); \pause
\end{tikzpicture}

With this change and two compiles, you should get an 6 page document that I think will do what you are looking for.

Code:

\documentclass[compress]{beamer}
\usetheme{Warsaw}
\usepackage{amsmath}
\usepackage{amssymb}
\usepackage{tikz}
\usetikzlibrary{arrows,shapes}

\tikzstyle{every picture}+=[remember picture]
\tikzstyle{na} = [baseline=-.5ex]

\begin{document}

\begin{frame}
\frametitle{Test}


\begin{itemize}
\item Overall mean \tikz[na] \node[coordinate] (s1) {};
\end{itemize}


\begin{equation}
y_{ijk} = \tikz[baseline]{ \node[fill=blue!20,anchor=base,rounded corners=2pt]
  (d1) {$\mu$}; }
+ \tikz[baseline]{ \node[fill=red!20,anchor=base,rounded corners=2pt]
  (d2) {$r_{i}$}; }
+ \tikz[baseline]{ \node[fill=green!20,anchor=base,rounded corners=2pt]
  (d3) {$c_{j}$}; }
+ \tikz[baseline]{ \node[fill=yellow!20,anchor=base,rounded corners=2pt]
  (d4) {$t_{k}$}; }
+ \epsilon_{ijk}
\end{equation}

\begin{itemize}
\item Effect of row $i$ \tikz[na] \node[coordinate] (s2) {};
\item Effect of column $j$ \tikz[na] \node[coordinate] (s3) {};
\item Effect of treatment $k$ \tikz[na] \node[coordinate] (s4) {};
\end{itemize}

\begin{tikzpicture}[overlay]
\path[->] (s1) edge [bend left] (d1);
\path[->] (s2) edge [bend right] (d2);
\path[->] (s3) edge [out=0, in=-90] (d3);
\path[->] (s4) edge [out=0, in=-90] (d4);
\end{tikzpicture}

\end{frame}

\end{document}

Thanks @Peter for your help. Using your suggestion there is no error but not still there is no animation. I wonder how to get the animation of arrows. Any idea. Thanks – MYaseen208 May 10 '12 at 05:25
@HarishKumar: Maybe I have a faster internet connection. :-) – Peter Grill May 10 '12 at 05:28
@MYaseen208: I don't see anything about animation in the code or the page you linked to. – Peter Grill May 10 '12 at 05:28
Sorry @PeterGrill, my bad! Would you mind to guide me how to animate these arrows. Thanks – MYaseen208 May 10 '12 at 05:33
@MYaseen208: I am not an expert in beamer, but perhaps the updated solution is what you are looking for. The only other animation I have experience with is Sieve of Eratosthenes in tikz – Peter Grill May 10 '12 at 05:40
@HarishKumar: There is a link in the Sieve animation I referenced above to an Answer Martin Scharrer provided using pdfcrop and ImageMagick's convert which generates a gif. – Peter Grill May 10 '12 at 08:04
In the example the blue footer appears only after the last animation slide. Is there a way to make this appear on every page during the animation? – Uwe Ziegenhagen May 10 '12 at 21:51
@UweZiegenhagen: Am sure there is, but I don't know enough about beamer. Perhaps post a separate question if you don't find that problem already addressed on this site. – Peter Grill May 10 '12 at 22:21
@HarishKumar: Did you have difficulty with getting an animated gif? – Peter Grill May 11 '12 at 20:37
@HarishKumar: Then you should post it to your answer below. I was just asking in case you needed help. – Peter Grill May 11 '12 at 22:49

This is supposed to be the supplement for @Peter Grill's solution regarding animation. One can use <1-> thing as in this MWE:

\documentclass[compress]{beamer}
\usetheme{Warsaw}
\usepackage{amsmath}
\usepackage{amssymb}
\usepackage{tikz}
\usetikzlibrary{arrows,shapes}

\tikzstyle{every picture}+=[remember picture]
\tikzstyle{na} = [baseline=-.5ex]

\begin{document}

\begin{frame}
\frametitle{Test}


\begin{itemize}
\item<2-> Overall mean \tikz[na] \node[coordinate] (s1) {};
\item<1->[]{%
\begin{equation}
y_{ijk} = \tikz[baseline]{ \node[fill=blue!20,anchor=base,rounded corners=2pt]
  (d1) {$\mu$}; }
+ \tikz[baseline]{ \node[fill=red!20,anchor=base,rounded corners=2pt]
  (d2) {$r_{i}$}; }
+ \tikz[baseline]{ \node[fill=green!20,anchor=base,rounded corners=2pt]
  (d3) {$c_{j}$}; }
+ \tikz[baseline]{ \node[fill=yellow!20,anchor=base,rounded corners=2pt]
  (d4) {$t_{k}$}; }
+ \epsilon_{ijk}
\end{equation}}%

\item<3-> Effect of row $i$ \tikz[na] \node[coordinate] (s2) {};
\item<4-> Effect of column $j$ \tikz[na] \node[coordinate] (s3) {};
\item<5-> Effect of treatment $k$ \tikz[na] \node[coordinate] (s4) {};
\end{itemize}


\begin{tikzpicture}[overlay]
\path<2->[->] (s1) edge [bend left] (d1);
\path<3->[->] (s2) edge [bend right] (d2);
\path<4->[->] (s3) edge [out=0, in=-90] (d3);
\path<5->[->] (s4) edge [out=0, in=-90] (d4);
\end{tikzpicture}

\end{frame}
\end{document}
