jtt: Number of JTTs in a graph

In sctyner/geomnet: Network Visualization in the 'ggplot2' Framework

Description

Number of jumping transitive triplets (JTT) in a graph. A JTT between three nodes i,j, and k is defined as the situation that when there is a (directed) edge from i to j and an edge from j to k there is also a direct edge from i to k. In an undirected situation we can think of any undirected edge as two directed edges between the two nodes involved.

Usage

jtt(data, from_id, to_id)

Arguments

data	data set
from_id	name of the variable of edge tails
to_id	name of the variable of edge heads

Examples

data(blood)
ggplot(data= blood$edges) + geom_net(aes(from_id=from, to_id=to), directed=TRUE) + theme_net()
jtt(blood$edges, "from", "to")
# this number is very high compared to the overall number of edges that are not self-loops
nrow(subset(blood$edges, from != to))
