View source: R/landscape_gen.R

Function to generate a random carrying capacity landscape obeying certain constraints. It distributes peaks uniformly within an N-ball, which is approximated by the overall Super-gaussian multiplier distribution. Peak heights and widths are chosen to satisfy a particular ration and to add up to the total desired niche 'volume'.

`potent_vol` |
Total potential volume of the entire landscape. |

`total_vol` |
Total approximate volume of the entire landscape. |

`num_peaks` |
Number of fitness peaks to place on the landscape. |

`h_to_sig_ratio` |
Ratio of the height of each peak to its width (or sigma value). |

`P_min_max` |
Vector of length 2 giving the minimum and maximum peak super-gaussian parameters to use. |

`dirichlet_param` |
The alpha parameter of the dircihlet distribution for determining how the volume should be split between the peaks. |

`d` |
The number of dimensions of the landscape |

`P` |
Super-gaussian parameter for whole landscape multiplier |

`a_prop` |
Minimum carrying capacity within the landscape as a proportion of the maximum height |

List of parameter values that can be used in the carrying capacity function to generate the landscape
