Description

The function losses calculates the yearly losses from a Gef or a ProdGCPV object. The function compareLosses compares the losses from several ProdGCPV objects and plots the result with dotplot.

Usage

compareLosses(...)
losses(object)

Arguments

...

A list of ProdGCPV objects to be compared.

object

An object of Gef or ProdGCPV class..
