Creates a Value Function for River Macrophytes

Description

Creates a value function for river macrophytes based on the Swiss modular concept for stream assessment 2017.

Usage

msk.macrophytes.2017.create(language     = "English",
                            dictionaries = NA,
                            col          = "black")
