Package: Rpath 1.1.0

Kerim Aydin

Rpath: R implementation of Ecopath with Ecosim

This package implements the core mass balance equations made popular by Ecopath with Ecosim. There are two parts to the package, the static snapshot of energy flow through the system using rpath and dynamic simulations run using the rsim family of functions.
