Landscape-class: Class "Landscape"

In tcarruth/SSES: Spatial Social Ecological Systems

Description

An S4 class object for storing all attributes of the landscape including anglers, population centres and lakes. Landscape objects can be modified, subsetted and adapted using a range of SSES functions.
