val.invertebrates.create {ecoval}

Creates an Integrative Value Function for River Invertebrates

Description

Creates a value function for river invertebrates integrating macroinvertebrate indices for organic matter pollution and toxicity.

Usage

val.invertebrates.create(language     = "English",
                         dictionaries = NA,
                         col          = "black",
                         modify       = TRUE)

Arguments

language

Language to be used to denote nodes, attributes and attribute levels. Must be a column name of the table provided by the second argument.

dictionaries

Matrix of dictionaries with the languages provided by the column names and the original words provided as the row names. If dictionary is NA, the default dictionary ecoval.dictionaries.default is loaded.

col

Color of bounding boxes in objectives hierarchy.

modify

Use the biological indicators Makroindex and IBGN in addition to IBCH. Default is TRUE.

Value

The function returns the value function as a class utility.
