community_graph: Create community graph

In memnet: Network Tools for Memory Research

Description

Create a graph from verbal fluency data by adding edges for words that occur within a window size l and retaining those that occur more frequently than min_cooc and the expectations number of chance productions co- occurences based on 1-crit.

Usage

community_graph(dat, l = 3L, min_cooc = 2L, crit = 0.05)

Arguments

dat	list of character vectors containing the fluency productions.
l	an integer specifying the window size. The internal upper limit of l is the number of productions.
min_cooc	integer specifying the minimum number of times two words have to coocur within a window size of l to consider including an edge between them.
crit	a numeric within [0,1] specifiying the type-1 error rate of including an edge between unconnected words.

Value

A matrix

Examples

# get animal fluency data
data(animal_fluency)

# infer influence network
inferred_network = community_graph(animal_fluency)

# Simulate -----

# generate watts strogatz graph
network = grow_ws(n = 200, k = 10, p = .5)

# generate fluency data
# sets string equal TRUE as community_graph expects mode character
fluency_data = fluency(get_adjlist(network), rep(10, 100), string = TRUE)

# infer fluency network
inferred_network = community_graph(fluency_data)
