  receiver,
  weighted = NULL,
  tobs = NULL,
  sym = FALSE,
  num.ids = FALSE
)

Arguments

actor	an integer or a string indicating the column of the individuals performing the behaviour.
receiver	an integer or a string indicating the column of the individuals receiving the behaviour.
weighted	an integer or a string indicating the column of the weights of interactions. If NULL, interactions are given a weight of 1.
tobs	an numeric vector or a list of numeric vectors of each individual time of observation. It has to be alphabetically ordered following unique id names.
