convert individual event information to aggregated information per network node
aggr_data(dat, from = NULL, cumsum = TRUE)data.frame of dimension (TxK), where T is the number of observation times and K the number of network nodes. Thus, each row represents a snapshot of the spreading process at a specific observation time with the event magnitude observed at the network nodes. Rownames are observation times, colnames are node names.
data.frame with variables 'node', 'time', 'delay', events data with single events with count magnitude
character in strftime format, e.g. "2014-06-12 16:15", data is subsetted accordingly before aggregation
logical indicating whether data is aggregated by cumulative sum, default is TRUE
