Retrieves chronological data from XRONOS. chron_data() retrieves all
records. Additional parameters can be used to filter the results.
chron_data(..., .everything = NA)(Optional) One or more named arguments specifying filter variables
and values to include. Supported filters are "labnr", "site",
"site_type", "country", "feature", "material", and "species".
If TRUE, suppresses interactive mode prompt when
retrieving all records from XRONOS (see details).
To reduce unnecessary server load, get_xronos() (without any filters) will
prompt for confirmation in interactive mode interactive mode. Set
.everything = TRUE to suppress this.
country should be a valid
ISO two-letter country code.
Otherwise, the function will try to interpret as such using
countrycode::countryname(), or return an error if any values of country
cannot be matched.
