In ecoval: Procedures for Ecological Assessment of Surface Waters

Creates a Value Function for River Diatoms

Description

Creates a value function for river diatoms based on the Swiss modular concept for stream assessment, level I (Regional survey) from 2007.

Usage

msk.diatoms.2007.create(language     = "English",
                        dictionaries = NA,
                        col          = "black")

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.

Value

The function returns the value function as a class utility.
