findPathLength: Cumulative Flow over a Range of Path Lengths

In SEELab/enaR: Tools for Ecological Network Analysis

Cumulative Flow over a Range of Path Lengths

Description

Calculates the flow throughout the entire network over a given path length.

Usage

findPathLength(x, maxPath = 100, plot.sw = FALSE)

Arguments

x	Network model object.
maxPath	The maximum path length to calculate total flow.
plot.sw	LOGICAL: should a plot be generated showing flow accumulation?

Value

thresholds	thresholds indicating the development of throughflow as path length increases: the path length at which indirect flow exceeds direct flow (mID), path length at which 50%, 90%, and 95% of total system throughflow is achieved (m50, m90, and m95, respectively)
tf	total flow across paths from length 0 (Boundary inputs) to maxPath
ctf	cumulative total flow from path length 0 to maxPath
