Function to investigate behaviour of AOO under various split scenarios

Description

gridUncertaintySimulation returns the maximum and minimum number of area of occupancy (AOO) grid cells occupied by a species or ecosystem in incremental splits using gridUncertaintyBase.

Usage

gridUncertaintySimulation(
  input.data,
  grid.size,
  simulations,
  min.percent.rule = FALSE,
  percent = 1
)

Arguments

input.data	Spatial object of an ecosystem or species distribution. Please use a CRS with units measured in metres.
grid.size	A number specifying the width of the desired grid square (in same units as your coordinate reference system)
simulations	Specifies the maximum number of splits to be performed on the generated grid
min.percent.rule	Logical. If TRUE, a minimum area threshold must be passed before a grid is counted as an AOO grid.
percent	Numeric. The minimum percent to be applied as a threshold for the min.percent.rule.

Value

Data frame of results showing the minimum and maximum AOO calculated for each grid shift scenario.
