Aggregate grid cell draws to polygons: validation

Description

Data validation for aggregate_draws_to_polygons

Usage

aggregate_draws_to_polygons_validation(
  draws_matrix,
  aggregation_table,
  aggregation_cols,
  method,
  z_dimension,
  z_dimension_name,
  weighting_raster,
  na.rm
)

Arguments

draws_matrix	matrix, array, or data.frame corresponding to grid cell draws that will be aggregated to polygons.
aggregation_table	data.table::data.table Aggregation table linking pixels to polygon identifiers, created using build_aggregation_table()
aggregation_cols	(character vector, default 'polygon_id') Polygon identifiers to use for aggregation.
method	(character, default 'mean') Aggregation method: one of 'mean', 'sum', 'weighted.mean', or 'weighted.sum'.
z_dimension	(vector, default NULL) If passing a draws_matrix with multiple sets of estimates, how should each layer be identified?
z_dimension_name	(default 'z') The field name for the "z" dimension corresponding to each set of estimates contained in draws_matrix.
weighting_raster	(terra::SpatRaster, default NULL) The relative weighting of each whole pixel to the overall polygon value, for example, if calculating a population-weighted mean.
na.rm	(bool, default TRUE) How to handle NA values in draws_matrix and weighting_raster.

Value

Errors if checks fail; silently passes if checks pass
