probInit: SELES - Probability of Initiation

Description

Describes the probability of initiation of agents or events. THIS IS NOT FULLY IMPLEMENTED.

A SELES-like function to maintain conceptual backwards compatability with that simulation tool. This is intended to ease transitions from http://www.gowlland.ca/{SELES}.

You must know how to use SELES for these to be useful.

Usage

probInit(map, p = NULL, absolute = NULL)

Arguments

map
A spatialObjects object. Currently, only provides CRS and, if p is not a raster, then all the raster dimensions.
p
probability, provided as a numeric or raster
absolute
logical. Is p absolute probabilities or relative?

Value

  • An RasterLayer with probabilities of initialization. There are several combinations of inputs possible and they each result in different behaviors.

    If p is numeric or Raster and between 0 and 1, it is treated as an absolute probability, and a map will be produced with the p value(s) everywhere.

    If p is numeric or Raster and not between 0 and 1, it is treated as a relative probability, and a map will be produced with p/max(p) value(s) everywhere

    If absolute is provided, it will override the previous statements, unless absolute is TRUE and p is not between 0 and 1 (i.e., is not a probability)
