gridUncertaintyRestricted determines the number of area of occupancy (AOO) grid
cells occupied by a species or ecosystem systematically. It will only stop
when the AOO calculated does not improve (decrease) after a set number of
split scenarios. The number of grids within each split is restricted to only
include those which are already found nearby to ones already with the minimum
AOO.
gridUncertaintyRestricted(input.data, grid.size, n.AOO.improvement,
min.percent.rule = FALSE, percent = 1)Object of an ecosystem or species distribution. Accepts either raster or spatial points formats. Please use a CRS with units measured in metres.
A number specifying the width of the desired grid square (in same units as your coordinate reference system)
Specifies the minimum number of rounds the calculated AOO is not improved before stopping the function.
Logical. If TRUE, a minimum area threshold
must be passed before a grid is counted as an AOO grid.
Numeric. The minimum percent to be applied as a threshold for
the min.percent.rule.
A list containing the following:
Data frame of results showing the minimum AOO calculated for each shift scenario
Single SpatialPolygonsDataFrame containing the AOO grid which would produce the minimum AOO calculated
