get site ids

Description

This uses the site boundary shapefile (obtainable by data('sites')) to get a list of siteID codes to feed into npe_download.

Usage

npe_site_ids(by = NA, domain = NA, type = NA, aridity = NA, koppen = NA)

Arguments

by

which variable to select sites by. Can be "domain", "ai", "koppen", or "type". Defaults to NA, which directs the function to return all site codes.

domain

can be one or more domain codes, as a character vector, or as a number. e.g. domain = c("D01", "D14"), or domain = c(3, 14), can also be a mix: domain = c(3, "D04).

type

can be "Core Terrestrial" or "Relocatable Terrestrial"

aridity

can be "Hyper-Arid", "Arid", "Dry sub-humid", or "Humid"

koppen

can be any 3 letter Koppen-Geiger code, or one of "Equatorial", "Arid", "Temperate", "Boreal", "Polar"

Value

a vector of four letter site identification codes.

Examples

# if no domains or site types are specified, it returns all site codes
all_sites <- npe_site_ids()
npe_site_ids(by = "domain", domain = c("Northeast", "Mid-Atlantic"))
npe_site_ids(by = "domain", domain = c("D02", 15))
