parse_family: Parse components of a "family-level" taxon name

In SoilTaxonomy: A System of Soil Classification for Making and Interpreting Soil Surveys

Parse components of a "family-level" taxon name

Description

Parse components of a "family-level" taxon name

Usage

parse_family(family, column_metadata = TRUE, flat = TRUE)

Arguments

family	character. vector of taxonomic families, e.g. "fine-loamy, mixed, semiactive, mesic ultic haploxeralfs"
column_metadata	logical. include parsed NASIS physical column names and values from family taxon components? Default: TRUE requires soilDB package.
flat	logical Default: TRUE to return concatenated family-level classes for "taxminalogy" and "taxfamother"? Alternately, if FALSE, list columns are returned.

Value

a data.frame containing column names: "family" (input), "subgroup" (parsed taxonomic subgroup), "subgroup_code" (letter code for subgroup), "class_string" (comma-separated family classes), "classes_split" (split class_string vector stored as list column).

In addition, the following column names are identified and returned based on NASIS (National Soil Information System) metadata (via soilDB package):

• "taxpartsize", "taxpartsizemod", "taxminalogy", "taxceactcl", "taxreaction", "taxtempcl", "taxfamhahatmatcl", "taxfamother", "taxsubgrp", "taxgreatgroup", "taxsuborder", "taxorder"

Examples

if (requireNamespace('soilDB')) {
  families <- c("fine, kaolinitic, thermic typic kanhapludults",
                "fine-loamy, mixed, semiactive, mesic ultic haploxeralfs",
                "euic, thermic typic haplosaprists",
                "coarse-loamy, mixed, active, mesic aquic dystrudepts")

  # inspect parsed list result
  str(parse_family(families))
}
