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)
Vector of databases to be retrieved, or "all".
(Optional) Vector of countries to be retrieved.
(Optional) Vector of sites to be retrieved.
If TRUE
(the default), the data retrieved will be combined
into a data frame. Set FALSE
to get the raw data from IntChron.
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.
