Sequential Berger-Parker's diversity index
Description
This function calculates the Berger-Parker's diversity index for each cell in a matrix, considering a specified moving window around each cell.
Usage
BergerParkerS(x, window = 1, na.tolerance = 1, debugging = FALSE)
Arguments
x |
A numeric matrix representing the data on which the index is to be calculated. |
window |
The width of the moving window to consider for each cell. The actual window size will be '(2 * window + 1) x (2 * window + 1)'. Default is 1. |
na.tolerance |
The tolerance level for missing data within the moving window. A window will be processed only if the proportion of non-missing data is above this threshold. Value should be between 0 and 1. Default is 1. |
debugging |
Boolean flag to enable or disable debugging messages. Default is FALSE. |
Details
Berger-Parker's diversity index calculated sequentially over a raster matrix.
Value
A matrix of the same dimensions as 'x', where each cell contains the Berger-Parker's diversity index calculated for the window around the cell.
Examples
data <- matrix(runif(100), nrow = 10)
bp_index <- BergerParkerS(data, window = 1)
