events2station: Transform an 'event' object into a 'station' object

In metno/esd: Climate analysis and empirical-statistical downscaling (ESD) package for monthly and daily data

Transform an 'event' object into a 'station' object

Description

Aggregate some aspects of an 'events' object in time and space and transform the time series into a 'station' object.

Usage

events2station(
  x,
  param = "count",
  FUN = "mean",
  verbose = FALSE,
  longname = NULL,
  unit = NULL,
  ...
)

Arguments

x	input object of class 'events'
param	parameter to aggregate, e.g., 'count' or some characteristic such as 'pcent' or 'radius' (for options, see names(x))
FUN	a function, e.g., 'mean' or 'sum'
verbose	a boolean; If TRUE print information about progress
longname	long name of variable
unit	name of unit
...	additional arguments
by.trajectory	a boolean; This input is only used when param is 'count'. See description above.
by	the time interval of aggregation, only used when param is 'count'. The default is "month", other options are "year", "day", and "timestep". When param is not 'count', by cannot be changed and the aggregation is always on a monthly time scale.

Details

If the aggregated aspect is the number of events (param='count', the default option), the events can be aggregated in several different ways. The frequency of aggregation can be set by the input parameter 'by' (default: "month"). If by.trajectory=FALSE (default), the function counts the average number of events per timestep at the selected interval. If by.trajectory=TRUE, the function instead counts the number of individual trajectories that are identified within that time period. The latter option requires 'track' to have been applied to the events.

Value

a 'station' object
