saveSWF

This function opens a graphical device first to generate a sequence of images
based on <code>expr</code>, then makes use of the commands in SWFTools
(<code class="command">png2swf</code>, <code class="command">jpeg2swf</code>, <code class="command">pdf2swf</code>) to convert these
images to a single Flash animation.

Provides functions for animations in statistics, covering topics
in probability theory, mathematical statistics, multivariate statistics,
non-parametric statistics, sampling survey, linear models, time series,
computational statistics, data mining and machine learning. These functions
may be helpful in teaching statistics and data analysis. Also provided in this
package are a series of functions to save animations to various formats, e.g.
Flash, 'GIF', HTML pages, 'PDF' and videos. 'PDF' animations can be inserted
into 'Sweave' / 'knitr' easily.

saveSWF function

<dl><dt>expr</dt>
<dd>an expression to generate animations; use either the animation
functions (e.g. <code>brownian.motion()</code>) in this package or a custom
expression (e.g. <code>for(i in 1:10) plot(runif(10), ylim = 0:1)</code>).</dd>
<dt>swf.name</dt>
<dd>file name of the Flash file</dd>
<dt>img.name</dt>
<dd>the base file name of the sequence of images (without any
format or extension)</dd>
<dt>swftools</dt>
<dd>the path of SWFTools, e.g. <code class="file">C:/swftools</code>. This argument
is to make sure that <code>png2swf</code>, <code>jpeg2swf</code> and <code>pdf2swf</code> can
be executed correctly. If it is <code>NULL</code>, it should be guaranteed that
these commands can be executed without the path; anyway, this function will
try to find SWFTools from Windows registry even if it is not in the PATH
variable.</dd>
<dt>...</dt>
<dd>other arguments passed to <code>ani.options</code>, e.g.
<code>ani.height</code> and <code>ani.width</code>, ...</dd></dl>
