hyet_aggregate uses an hyetograph, single or grouped
(i.e. from hyet_split) and a predefined time-step to aggregate
precipitation records. Returns an error if hyet is not a valid
hyetograph.
hyet_aggregate(hyet, time_step, ts_unit)
| hyet | an hyetograph from   | 
    
|---|---|
| time_step | a numeric value that represents the time-step.  | 
    
| ts_unit | a character string specifying the time unit. Valid values are "mins", "hours", "days", "months", "quarter" or "year".  | 
    
a tibble with the aggregated hyetograph.
