This function returns a vector with the timeseries of event IDs
according to the input keep column of the dataframe.
Usage
get_event_ids(df)
Value
a vector of the same length as the rows of the input dataframe with
the timeseries of event IDs.
Arguments
df
A dataframe with a set and a keep column to get the timeseries of
event IDs. The keep column is added by the
define_events function and represents whether each timestep is
part of an event or not (whether it should be kept in for the rest of the
analysis). Each set of the dataframe should be ordered in time.
