Assign standard forest unit based on species composition and additional criteria

Description

This function uses a set of rules to assign standard forest unit (SFU or just FU) based on forest composition, region and additional parameters that depend on the selected region.

Usage

species2unit(
  species_composition,
  region,
  ecosite = NA,
  WG = NA,
  age = NA,
  site_class = NA,
  stocking = 1
)

Arguments

species_composition	This can be: (1) A data frame with two columns - first column has to contain species code, the second has to contain species proportion (species proportions should sum up to 1); (2) a string containing information on species composition. Note that this string has to be formated as follows: PW 60PR 40, or PW 60 PR 40, or PW60 PR40.
region	Region number (1-3)
ecosite	Id of ecosite, required for Region 1. Eg.: NW17
WG	Working group, required for Region 1.
age	Stand age, required for Region 1.
stocking	Stocking, required for Region 3. Default = 1
site_class.	Site class (1-4), required for Region 2 and 3.

Value

Standard forest unit code

Examples

species2unit(species_composition = "PR 90 BW 10", region = 2, site_class = 1)

species2unit(species_composition = "SB  80SW   5LA   5BW   5BF   5", region = 2, site_class = 2)
