In SEELab/enaR: Tools for Ecological Network Analysis

Control Analyses of Ecological Networks

Description

Analyses for analyzing the control amongst the nodes in ecological networks.

Usage

enaControl(x, zero.na = TRUE, balance.override = FALSE)

Arguments

x	A network object.
zero.na	Makes undefined (NA) values zero.
balance.override	Turns off balancing and checks of network balance.

Value

CN	Control matrix using flow values.
CQ	Control matrix using storage values.
CR	Schramski Control Ratio Matrix
CD	Schramski Control Difference Matrix
CA	Control Allocation Matrix
CDep	Control Dependency Matrix
sc	Schramski System Control vector
scp	Schramski system control vector as percent of total control
ns	vector of network-level summary statistics
