Query IntChron

IntChron is an indexing service for chronological data from multiple sources. This function gets records from databases ('hosts') indexed by IntChron, optionally filtering by country and/or site.

intchron(hosts, countries = NA, sites = NA, tabulate = TRUE)

Arguments

hosts

Vector of databases to be retrieved, or "all".

countries

(Optional) Vector of countries to be retrieved.

sites

(Optional) Vector of sites to be retrieved.

tabulate

If TRUE (the default), the data retrieved will be combined into a data frame. Set FALSE to get the raw data from IntChron.

Value

A tibble, or if tabulate = FALSE, a list, of IntChron responses.

Details

At least hosts must be specified. Use intchron_hosts() to get a list of currently available hosts, or "all" to retrieve data from any database.

See vignette("rintchron") for further details.
