Classify irrigation adequacy (AETI / ETc)

Wrapper for wapor_classify() with scheme "adequacy". Formula: class of the ratio AETI/ETc. Default breaks 0.68, 0.80, 1.00 (poor / acceptable / good / above ETc). Class 4 is a package extension, not a published over-irrigation class; for deficit irrigation, rainfed crops and salinity, a "poor" class can be intended management.

Usage

wapor_classify_adequacy(adequacy, breaks = NULL, labels = NULL, right = TRUE)

Source

Karimi et al. (2019); Chukalla et al. (2022).

Arguments

adequacy

Numeric vector or SpatRaster of AETI/ETc.

breaks, labels, right

Passed to wapor_classify().

Value

A factor or categorical SpatRaster.
