The function `betadiversity`

estimates the beta diversity as the
instantenous rate of change at any gradient point.

1 2 3 |

`object` |
A response frame object: Fitted models for species. |

`x` |
Gradient values. |

`type` |
Type of graph. |

`xlab, ylab` |
Axis labels; defaults provided if these are missing. |

`splines` |
Use interpolating |

`...` |
Other parameters. |

The function finds the instantenous rate of change along the gradient from the fitted response functions for species.

Currently the function is implemented for `HOF`

models
only.

The function has a `plot`

method.

The function returns an object of class `"betadiversity"`

with
the following items:

`x ` |
Used gradient values. |

`beta ` |
Beta diversity at the gradient points. |
