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