get_development: Get the beetles development

In barrks: Calculate Bark Beetle Phenology Using Different Models

Get the beetles development

Description

Get the beetles development of specific generations. A value of -1 implies that the generation is not present yet.

Usage

get_development_rst(pheno, generation, dates = prop_dates(pheno))

get_development_df(
  pheno,
  stations = prop_stations(pheno),
  generation = prop_hatched_generations(pheno),
  dates = prop_dates(pheno)
)

Arguments

pheno	A phenology (see phenology())
generation	Generation of interest. For sister broods, 0.5 should be added. get_development_df() allows multiple generations here.
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

• get_development_rst(): A multi-layer SpatRaster.

• get_development_df(): A data frame which contains a field for each generation (gen_1, gen_1.5, gen_2, gen_2.5, ...) requested.

Examples

# calculate station-based phenology
p <- phenology('phenips-clim', barrks_data('stations'), .quiet = TRUE)

# print the development data frame of station 'Freiburg'
df <- get_development_df(p, 'Freiburg')
df[,4:ncol(df)] <- round(df[,4:ncol(df)], 3) # round results
df
