USDA Soil Taxonomy diagnostic features canonical table — st_features

Convenience wrapper for canonical_reference("ST_features"). Returns an 84-row data.frame with one row per diagnostic feature (epipedon / subsurface horizon / property / material) and columns: group, name, chapter, page, description, criteria. The criteria column is a list-column; each element holds the parsed criteria text per feature.

Usage

st_features_canonical(prefer_pkg = TRUE)

Arguments

prefer_pkg: If TRUE (default), prefer the installed SoilTaxonomy package over the vendored copy. Set to FALSE to force the vendored copy (e.g. for reproducibility of a specific soilKey release).
