Normalise FEBR USDA taxon strings to USDA Soil Taxonomy Order

FEBR ships USDA Soil Taxonomy labels at the subgroup or great-group granularity (e.g. "TYPIC HAPLUDULT", "ACRUSTOX"). The suffix of the final word encodes the Order: ...OX -> Oxisols, ...ULT -> Ultisols, ...EPT -> Inceptisols, etc. This helper extracts the Order from the suffix so the benchmark can compare against classify_usda()$rsg_or_order at level = "order".

Usage

normalise_febr_usda(x)

Arguments

x

Character vector of FEBR USDA names.

Value

Character vector of normalised Order names ("Oxisols", "Ultisols", "Inceptisols", ...).
