MNS (version 1.0)

MNS-package: Mixed Neighbourhood Selection package

Description

An R package for estimating multiple, related grapical models using the Mixed Neighbourhood Selection algorithm. This package also includes two algorithm through which to simulate multiple, related graphical models which demonstrate some of the properties reported through empirical studies of functional connectivity networks.

## Not run: 
# # plot simulated networks:
# plot(Net, view="pop")

# # run MNS algorithm:
# mns = MNS(dat = Net$Data, lambda_pop = .1, lambda_random = .1, parallel = TRUE)
# 
# # plot results from MNS algorithm:
# plot(mns) # plot population network
# plot(mns, view="var") # plot variance network
# plot(mns, view="sub") # plot subject networks (note red edges here are variable edges!)
