getAbundanceAnomaly {vectorsurvR}

Get Abundance Anomaly

Description

'getAbundanceAnomaly(...) 'requires at least five years prior to the target_year of arthro collections data to calculate for the specified parameters. The function uses the methods of the Gateway Abundance Anomaly calculator, and will not work if there is fewer than five years of data present.

Usage

getAbundanceAnomaly(
  collections,
  interval,
  target_year,
  species_list = NULL,
  trap_list = NULL,
  species_separate = FALSE
)

Arguments

collections

Collections data retrieved from 'getArthroCollections()'

interval

Calculation interval for abundance, accepts “collection_date”,“Biweek”,“Week”, and “Month

target_year

Year to calculate analysis on. Collections data must have a year range of at least (target_year - 5, target_year)

species_list

Species filter for calculating abundance. Species_display_name is the accepted notation.To see a list of species present in your data run 'unique(collections$species_display_name)'. If species is unspecified, the default NULL will return data for all species in data

trap_list

Trap filter for calculating abundance. Trap_acronym is the is the accepted notation. Run 'unique(collections$trap_acronym)' to see trap types present in your data. If trap_list is unspecified,the default NULL will return data for all trap types

species_separate

Should the species in species_list have abundance calculated separately? Setting to FALSE calculates the combined abundance. The same result can be performed by calculating on one species at the time description

Value

Abundance anomaly calculation

Examples

getAbundanceAnomaly(sample_collections,"Biweek",target_year=2020, species_list="Cx pipiens")
