bso_get_flight: Get flight of individuals (BSO only)

In barrks: Calculate Bark Beetle Phenology Using Different Models

Get flight of individuals (BSO only)

Description

Get the number of individuals that are flying.

Usage

bso_get_flight_rst(pheno, generation, flight = 1, dates = prop_dates(pheno))

bso_get_flight_df(
  pheno,
  generation,
  stations = prop_stations(pheno),
  flight = 1,
  dates = prop_dates(pheno)
)

Arguments

pheno	A BSO phenology (see bso_phenology())
generation	Generation of interest. For sister broods, 0.5 should be added.
flight	Specifies which flight of the respective generation should be returned. Can be 1 (first flight) or 2 (second flight).
dates	Select dates that should be present in the output.
stations	Pass a character vector to choose stations assigned to pheno by their names, or pass different stations. See stations_create() for details.

Value

• bso_get_flight_rst: a multi-layer SpatRaster.

• bso_get_flight_df: a data frame.

Examples

# This may take a few minutes...

# calculate phenology
p <- bso_phenology('bso', barrks_data('stations'), .quiet = TRUE)

# get the number of individuals of the hibernating generation on their first flight
bso_get_flight_df(p, 0, 'Freiburg', flight = 1)
