Construct an Empty “Template” Network Consistent with an Egocentric Sample

Description

Taking a egor object, constructs a network object with no edges whose vertices have the attributes of the egos in the dataset, replicating the egos as needed, and taking into accounts their sampling weights.

Usage

template_network(x, N, scaling = c("round", "sample"), ...)

Arguments

x	A egor object.
N	The target number of vertices the output network should have.
scaling	If egor contains weights or N is not a multiple of number of egos in the sample, it may not be possible, for a finite N to represent each ego exactly according to its relative weight, and scaling controls how the fractional egos are allocated: "round" (the default) Rather than treating N as a hard setting, calculate N w_i / w_\cdot for each ego i and round it to the nearest integer. Then, the N actually used will be the sum of these rounded freqencies. "sample" Resample in proportion to w_i.
...	Additional arguments, currently unused.

Value

A network object.

Examples

data(faux.mesa.high)
summary(faux.mesa.high, print.adj = FALSE)

fmh.ego <- as.egor(faux.mesa.high)

# Same actor attributes
fmh.template <- template_network(fmh.ego, N=network.size(faux.mesa.high))
summary(fmh.template, print.adj = FALSE)

# Twice the actors, same distribution
fmh2.template <- template_network(fmh.ego, N=2*network.size(faux.mesa.high))
summary(fmh2.template, print.adj = FALSE)
