In rasterdiv: Diversity Indices for Numerical Matrices

Area-Based Sequential Parametric Rao's index of quadratic entropy (Q)

Description

Calculates an area-based sequential version of the parametric Rao's index of quadratic entropy (Q). This function is designed for situations where the diversity index needs to consider geographical areas and works with raster data representing the distribution of species or other measures.

Usage

mpaRaoAreaS(rasterm, area, alpha, simplify, dist_m, rescale, lambda, window)

Arguments

rasterm	Raster; the input raster data representing variables across a geographic space.
area	Numeric; the input vector data representing the areas of interest.
alpha	Numeric; alpha value for order of diversity in Hill's Index.
simplify	Numeric; the parameter that determines the rounding off of the calculations.
dist_m	Character; type of distance metric used (e.g., "euclidean", "manhattan", etc.).
rescale	Logical; whether to scale and centre the values in each element of the raster data.
lambda	Numeric; lambda parameter for Minkowski distance calculation.
window	Numeric; defines the size of the moving window for the analysis.

Value

A vector similar to the input, with additional columns representing Rao's index values for each area.
