subtract_networks: Subtract one network from another

In Nestimate: Network Estimation, Bootstrap, and Higher-Order Analysis

Subtract one network from another

Description

Returns x - y as a netdifference object: the element-wise difference of the two weight matrices. Works on any pair of networks; for an edge-betweenness difference, subtract two net_edge_betweenness results. Draw the signed difference network with cograph::splot(d) or cograph::plot_difference(d); cograph handles the colouring and node palette.

Usage

subtract_networks(x, y)

## S3 method for class 'netdifference'
print(x, max_print = 12L, ...)

Arguments

x, y	A netobject, cograph_network, or numeric square matrix. Both must share the same nodes in the same order.
max_print	Integer. Rows to show in print(). Default 12.
...	Ignored.

Value

A netdifference object: a netobject whose $weights and $difference_matrix are x - y, carrying the source matrices $x and $y.

Examples

seqs <- data.frame(
  V1 = c("A","B","A","C","B","A"), V2 = c("B","C","B","A","C","B"),
  V3 = c("C","A","C","B","A","C"))
a <- build_network(seqs, method = "relative")
b <- build_network(seqs[1:4, ], method = "relative")
subtract_networks(a, b)
# edge-betweenness difference:
subtract_networks(net_edge_betweenness(a), net_edge_betweenness(b))
