compress_ids: Remove non-active nodes from one-mode/two-mode/longitudinal networks

Description

The compress_ids function removes non-active nodes from one-mode/two-mode/longitudinal networks.

Usage

compress_ids(net,type=NULL)

Arguments

net

A network in an edgelist or matrix format. See as.tnet

type

See as.tnet

Value

Returns a list with either 2 or 3 objects. The first one is the network with the compressed id. The second object is the translation table between the original node identification numbers and the newly assigned. For two-mode networks, the second object is the translation table of the primary nodes, and the third object is the translation table for the secondary nodes .
