`meteSSF`

calculates the “spatial structure
function” *Π(n)* (analogous to the ecosystem structure function). From
the SSF the spatial abundance distribution can be calculated.

`spp` |
A vector of species names |

`sppID` |
A character giving the name of the desired species (as it appears in ‘spp’) |

`abund` |
A vector of abundances |

`row` |
A vector of row IDs for each observation |

`col` |
A vector of column IDs for each observation |

`x` |
A vector of x coordinates for each observation |

`y` |
A vector of y coordinates for each observation |

`n0` |
Total abundance in area A0 |

`A` |
The area at which abundances were recorded |

`A0` |
Total study area |

Uses either data or state variables to calculate the Spatial Structure Function (SSF). Uses internal code to determine when computation-saving approximations can be safely made

An object of class `meteSSF`

`data`

The data used to construct the SSF

`La`

Vector of Lagrange multipliers

`La.info`

Termination information from optimization procedure

`state.var`
