Composite fire events in fhx object

Description

Composite fire events in fhx object

Usage

composite(
  x,
  filter_prop = 0.25,
  filter_min_rec = 2,
  filter_min_events = 1,
  injury_event = FALSE,
  comp_name = "COMP"
)

Arguments

x	An fhx object.
filter_prop	The minimum proportion of fire events in recording series needed for fire event to be considered for composite. Default is 0.25.
filter_min_rec	The minimum number of recording series needed for a fire event to be considered for the composite. Default is 2 recording series.
filter_min_events	The minimum number of fire scars needed for a fire event to be considered for the composite. Default is 1. Fire injuries are included in this count if injury_event is TRUE.
injury_event	Boolean indicating whether injuries should be considered events. Default is FALSE.
comp_name	Character vector of the series name for the returned fhx object composite series. Default is 'COMP'.

Value

An fhx object representing the composited series. The object will be empty if there are nocomposite-worthy events.

Examples

data(lgr2)
plot(composite(lgr2))

# Use with composite to get composite years:
comp <- composite(pgm, comp_name = "pgm")
event_yrs <- get_event_years(comp)[["pgm"]]
print(event_yrs)
