BergerParkerP: Calculate Berger-Parker Index on a Matrix

Description

This function computes Berger-Parker Index for each cell of a matrix, using a parallelized approach and considering a specified moving window.

Usage

BergerParkerP(x, window = 1, na.tolerance = 1, debugging = FALSE, np = 1)

Value

A matrix of the same dimensions as `x`, where each cell contains the Berger-Parker Index calculated for the window around the cell.

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.

np

The number of processes (cores) which will be spawned. Default value is 2.

Examples

if (FALSE) {
data <- matrix(runif(100), nrow = 10)
bp_index <- BergerParkerP(data, window = 1, np=2)
}
