A classification scheme

Description

This class stores the information about a classification scheme, for example a biome classification scheme. It describes what how the model output (in the form of a data.table) must be prepared, and then the rules which are used to do the classification.

Slots

id: A unique character string to identify this particular classification scheme. Recommended to be alphanumeric because it is used to construct file names. (Inherited from Quantity via "contains")
name: A character string that can be more descriptive of the classification scheme. (Inherited from Quantity via "contains")
units: A list of character strings giving the names of categories. (Inherited from Quantity via "contains")
colours: A function that returns the colour scale for this Scheme. (Inherited from Quantity via "contains")
format: Either a the string "Standard" to denote that this is a standard quantity to be compared across all model and data, the id of the Format object with which this Quantity is associated.
rules: A function which is applied to every row of the data.table and describes the classification rules.
layers.needed: List of vegetation layers needed to perform the classification and the name of the new layer, to be interpreted by layerOp, specified as a list of three- or four-item list whose elements first element id the id of a Quantity and whose other elements are passed as arguments to the layerOp function. For example one element could be Woody = list(quantity = "LAI_std", operator = "+", layers = c(".Tree", ".Shrubs"), new.layer = "Woody"), which would make a layer called "Woody" which would be the sum of all LAI trees and shrubs.
data.reference: Character string giving a reference where the data for this classification scheme comes from
published.reference: Character string giving a reference where this model output classification scheme was published
