Classify a Mosaic Based on Index Breaks

Description

This function classifies a given raster mosaic based on user-defined breaks. It provides an option to calculate the frequency and area of each class, as well as plot the classified mosaic.

Usage

mosaic_classify(mosaic, breaks, frequency = TRUE, plot = TRUE)

Arguments

`mosaic`	A `SpatRaster` object representing the mosaic to be classified.
`breaks`	A numeric vector specifying the breakpoints for classification.
`frequency`	Logical. If `TRUE`, computes the class frequency and area (in hectares).
`plot`	Logical. If `TRUE`, plots the classified mosaic.

Value

A list with two elements:

classified: A SpatRaster object containing the classified mosaic.
class_freq: A data frame containing class frequencies, areas (ha), and percentages (if frequency = TRUE).

Examples

if(interactive()){
library(pliman)
library(terra)

# Create an example raster
r <- terra::rast(matrix(runif(100, min = 0, max = 1), nrow=10, ncol=10))

# Classify the raster
result <- mosaic_classify(r, breaks = c(0.3, 0.6))

# View results
result$classified
result$class_freq
}
