antsMersch: Dynamic contact network of ants

In dynsbm: Dynamic Stochastic Block Models

Dynamic contact network of ants

Description

Colonies of the ant Camponotus fellah were followed with a tracking system that monitored the individual positions over days of observations and dynamic social interactions were deduced from physical proximity. The data corresponds to a colony of N=152 ants observed during T=10 days. Edge weights were binned into K=3 categories corresponding to low, medium and high interaction intensity.

Usage

data(antsMersch)

Format

An array of size 10x152x152.

Examples

data(antsMersch)

## better to use nstart>>1 starting points
## but estimation can be long;
## better to use nb.cores>1 cores
list.dynsbm <- select.dynsbm(antsMersch, 
				Qmin=1, Qmax=6, edge.type="discrete", K=3, 
				nstart=1, nb.cores=1) 
				

## selection of Q=3 with the 'elbow' method
dynsbm <- list.dynsbm[[3]]

## plotting intra/inter connectivity patterns
connectivity.plot(dynsbm, antsMersch)
