Decompose taxon letter codes

Find all codes that logically comprise the specified codes. For instance, code "ABC" ("Anhyturbels") returns "A" ("Gelisols"), "AB" ("Turbels"), "ABC" ("Anhyturbels"). Use in conjunction with a lookup table that maps Order, Suborder, Great Group and Subgroup taxa to their codes (see taxon_code_to_taxon and taxon_to_taxon_code).

decompose_taxon_code(codes)

Arguments

codes

A character vector of taxon codes to "decompose" – case sensitive

Value

A list with equal length to input vector; one character vector per element

Details

Accounts for Keys that run out of capital letters (more than 26 subgroups) and use lowercase letters for a unique subdivision within the "fourth character position."
