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: Retained for compatibility and no longer used. Until v0.9.203 FALSE selected a copy bundled with soilKey; there is no bundled copy any more, so the data always come from SoilTaxonomy.

Value

The canonical Soil Taxonomy diagnostic-features reference (a list / data.frame).
