Compute Seasonal Standard Deviation (Variability) — wapor_calc_seasonal_std • Rwapor

Applies dekadal season weights to compute weighted standard deviation of rasters, and optionally summarizes by crop class.

Usage

wapor_calc_seasonal_std(
  x,
  season_weights,
  crop_mask = NULL,
  layer_multipliers = NULL,
  incremental = FALSE
)

Arguments

x: SpatRaster. Dekadal layers of any variable.
season_weights: SpatRaster. Dekadal season weights (0-1).
crop_mask: SpatRaster. Optional crop mask for per-class summaries.
layer_multipliers: Optional numeric vector of per-layer multipliers.
incremental: Logical. If TRUE, performs aggregation layer-by-layer to save memory.

Value

A list with:

raster: SpatRaster of seasonal weighted standard deviation per pixel
by_class: data.frame of mean seasonal standard deviation per crop class (if crop_mask provided)
