Get individuals (BSO only)

Description

Get the number of individuals of a generation that are in a specific development stage.

Usage

bso_get_individuals_rst(
  pheno,
  generation,
  stage = "all",
  dates = prop_dates(pheno)
)

bso_get_individuals_df(
  pheno,
  generation,
  stations = prop_stations(pheno),
  stage = "all",
  dates = prop_dates(pheno)
)

Arguments

pheno	A BSO phenology (see bso_phenology())
generation	Generation of interest. For sister broods, 0.5 should be added.
stage	If it is a numeric, the individuals of the slots specified will be retrieved. Otherwise it could be one of the following values: all, egg, larva, pupa, white (egg + larva + pupa), maturation, preflight, reproduction, brown (maturation + preflight + reproduction)
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_individuals_rst(): a multi-layer SpatRaster.

• bso_get_individuals(): 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 that are waiting to fly
bso_get_individuals_df(p, 0, 'Freiburg', stage = 'preflight')
