#' Social evolution of a university dormitory cohort

#' An abbreviated version of the MIT Reality Commons Social Evolution dataset,
#' spanning a reduced time period and with fewer variables. Dyadic variables
#' include binary friendships at time of survey, and time-stamped phone call
#' occurrences. Individual variables include the floor of the dormitory on
#' which the student resides, and the grade type of each student including
#' freshmen, sophomore, junior, senior, or graduate tutors.
