#' Network of interactions within a primary school in the course of a day
#' 
#' This network, collected and analyzed by J. Stehle et al. in "High-resolution measurements of face-to-face contact patterns in a primary school", records physical interactions between 226 children and 10 teachers within a primary school over the course of a day. The network data was collected using a system of sensors worn by the participants. This system records the duration of interactions between two individuals facing each other at a maximum distance of one and a half meters.
# 'The duration of these interactions varies between 20 seconds and two and a half hours. We consider that a physical interaction has been observed if the corresponding interaction duration is greater than one minute. If an interaction of less than one minute is observed, we consider that this observation may be erroneous, and treat the corresponding data as missing.
