load_regional_stats: Load regional summary statistics

Description

Load seasonal summary statistics for regions consisting of countries and states/provinces.

Usage

load_regional_stats(
  species,
  path = ebirdst_data_dir(),
  force = FALSE,
  show_progress = interactive()
)

Value

A data frame containing regional summary statistics with columns:

• species_code: alphanumeric eBird species code.

• region_type: country for countries or state for states, provinces, or other sub-national regions.

• region_code: alphanumeric code for the region.

• region_name: English name of the region.

• continent_code: alphanumeric code for continent that this region belongs to.

• continent_name: name of the continent that this region belongs to.

• season: name of the season that the summary statistics were calculated for.

• abundance_mean: mean relative abundance in the region.

• total_pop_percent: proportion of the seasonal modeled population falling within the region.

• continent_pop_percent: proportion of the seasonal modeled population for the continent (identified by continent_name) falling within the region.

• max_week: the week of the year with the highest proportion of the modeled population falling within the region.

• max_week_percent_pop: the proportion of the modeled population falling within the region in max_week, i.e. the maximum weekly value.

• range_occupied_percent: the proportion of the region occupied by the species during the given season.

• range_total_percent: the proportion of the species seasonal range falling within the region.

• range_days_occupation: number of days of the season that the region was occupied by this species.

Arguments

species

character; the species to load data for, given as a scientific name, common name or six-letter species code (e.g. "woothr"). The full list of valid species is in the ebirdst_runs data frame included in this package. To download the example dataset, use "yebsap-example".

path

character; directory to download the data to. All downloaded files will be placed in a sub-directory of this directory named for the data version year, e.g. "2020" for the 2020 Status Data Products. Each species' data package will then appear in a directory named with the eBird species code. Defaults to a persistent data directory, which can be found by calling ebirdst_data_dir().

force

logical; if the data have already been downloaded, should a fresh copy be downloaded anyway.

show_progress

logical; whether to print download progress information. Defaults to interactive(), so downloads are silent in non-interactive sessions (e.g. scripts and R Markdown).

Examples

if (FALSE) {
# download example data if hasn't already been downloaded
ebirdst_download_status("yebsap-example")

# load configuration parameters
regional <- load_regional_stats("yebsap-example")
}
