Determine relative position of taxon within Keys to Soil Taxonomy (Order to Subgroup)

The relative position of a taxon is [number of preceding Key steps] + 1, or NA if it does not exist in the lookup table.

relative_taxon_code_position(code)

Arguments

code	A character vector of taxon codes to determine the relative position of.

Value

A numeric vector with the relative position of each code with respect to their individual Keys.

Examples

# "ABCD" -> "Gypsic Anhyturbels", relative position 7
# "WXYZa" does not exist, theoretical position is 97
# "BAD" -> "Udifolists", relative position is 5

relative_taxon_code_position(c("ABCD", "WXYZa", "BAD"))
#>  ABCD WXYZa   BAD 
#>     7    NA     5 

# [1]  7 NA  5
