Calculate stability from deviation — stabilityCalc • climateStability

A function to calculate stability based on the results of `deviationThroughTime`.

stabilityCalc(rasterForCalculation)

Arguments

rasterForCalculation: A `SpatRaster` object that contains data from which stability is to be calculated.

Value

A raster

Details

This formula takes the inverse of the raster and rescales it from 0 to 1.This function is necessary in cases where there is no deviation in some cells. If time slices are very close together, it's possible that some cells may have values equal to zero, at which point if you simply divide 1 by the raster and rescale the result, you can end up with a raster full of zeroes.
