Classify vegetation plots with the expert system

resy_classify.Rd

Convenience wrapper that loads an expert system (by file or by scheme/version), aggregates taxa, evaluates membership conditions/expressions, and returns plot classifications.

Usage

resy_classify(
  obs,
  header,
  expertfile = NULL,
  scheme = "EUNIS",
  version = NULL,
  location = c("user", "package"),
  id_col = NULL,
  mc = max(1L, floor(parallel::detectCores() * 0.75))
)

Arguments

obs

Observations as `data.table` with at least columns describing plot id, `TaxonName`, and `Cover_Perc`.

header

Plot header data.frame; required for evaluating $$C/$$N.

expertfile

Optional path to expert-system file (.json/.txt). If set, takes precedence.

scheme

Scheme name (default: "EUNIS").

version

Version identifier. If NULL, uses latest available version for the scheme.

location

Where to look for scheme/version "user" or"package".

id_col

Optional name of the plot id column. If NULL, tries PlotObservationID, then PlotID.

mc

Number of CPU cores to use.

Value

An object of class `resy_result`.
