\title{Animation of branching random diffusion}
\usage{
branching.diffusion(sig2=1, b=0.0023, time.stop=1000, ylim=NULL,
smooth=TRUE, pause=0.02, record=NULL, path=NULL)
}
\arguments{
\item{sig2}{variance of BM process.}
\item{b}{birthrate for branching process.}
\item{time.stop}{number of generations to run.}
\item{ylim}{y limits (for plotting).}
\item{smooth}{no longer used.}
\item{pause}{pause (in s) between generations.}
\item{record}{filename for video file output (no video if \code{NULL}).}
\item{path}{full path to file for video rendering (by default is \code{C:/Program Files/ffmpeg/bin/ffmpeg.exe}).}
}
\description{
This function creates an animation of branching random diffusion (i.e., BM with speciation).
}
\value{
An animated plot and (optionally) a recorded video file. For animation to be recorded to file, the function requires the package "animation" as well as a video renderer.
