Canonicalise a USDA Great Group label to a KST 13ed-compatible key

Source: R/benchmark-kssl-gpkg.R
canonicalise_kst13ed_gg.Rd

Maps both obsolete (pre-KST 13ed) and modern Great Group names to a single canonical key, so that direct equality between predicted and reference Great Group names ignores edition-driven renaming. Names that have no known mapping pass through unchanged.

Usage

canonicalise_kst13ed_gg(gg)

Arguments

gg

Character vector of Great Group names (lower case, no whitespace).

Value

Character vector of canonical keys. Unmapped names pass through. NA stays NA. Empty input returns empty vector.

Details

Examples of the canonicalisation (each pair is rendered equivalent):

  • "haplaquolls" (KST 8) === "endoaquolls" (KST 13ed)

  • "pellusterts" (KST 8) === "hapluderts" (KST 13ed)

  • "camborthids" (KST 8) === "haplocambids" (KST 13ed)

  • "vitrandepts" (KST 8) === "vitrudands" (KST 13ed)
