twolayernetworkSimulation: Illustration of two-layer weighted network simulation

In fairmiracle/AMOUNTAIN: Active modules for multilayer weighted gene co-expression networks: a continuous optimization approach

Description

Simulate a two-layer weighted network

Usage

twolayernetworkSimulation(n1, k1, theta1, n2, k2, theta2)

Arguments

n1	number of nodes in the network1
k1	number of nodes in the module1, n1 < k1
theta1	module1 node score follow the uniform distribution in range [theta1,1]
n2	number of nodes in the network2
k2	number of nodes in the module2, n2 < k2
theta2	module2 node score follow the uniform distribution in range [theta2,1]

Value

a list containing network1, network2 and a inter-layer links matrix
