tree.grow

Creates an animation of a tree growing from left-to-right or upwards

Description

This function simulates a birth-death tree under user-defined conditions and then creates an animation of that tree growing from left-to-right in the plotting device, or upwards.

Usage

tree.grow(..., res=200, direction="rightwards", ladderize=TRUE)

Arguments

`...`	arguments to pass to `pbtree`.
`res`	number of steps (the resolution of the animation). This also corresponds to the number of frames that will be created if the animation is to be converted to a .gif file.
`direction`	the direction to plot the tree. Only `direction="rightwards"` (the default) and `direction="upwards"` are supported.
`ladderize`	logical value indicating whether or not to 'ladderize' the plotted tree. (Defaults to `TRUE`.)
