add_window_l {tnet}

Add smoothing window to a longitudinal network

Description

This function adds negative ties (i.e., a smoothing window) to a longitudinal network.

Usage

add_window_l(net,window=21, remove.nodes=TRUE)

Arguments

net

Longitudinal network

window

Number of days before ties 'expire'.

remove.nodes

Whether or not nodes should be removed from the network if they have no more ties. This function adds a self-loop with a negative weight at the time of a node's last tie plus the length of the window.
