Apply registers-style datatypes to fields

Registers use their own datatypes. This function converts character vectors to the equivalent R datatypes, handling cardinality='n'.

rr_apply_datatype(x, datatype, cardinality = 1, apply_iso_8601 = TRUE)

Arguments

x	Character vector (a field of a register).
datatype	Name of the datatype to apply: currently one of "curie", "url", "datetime", "string", "integer", "text", and "point". Unrecognised datatypes will be returned as characters.
cardinality	Character, one of "1" and "n" to say whether each element of x contains multiple values separated by semicolons.
apply_iso_8601	Logical, whether to parse ISO8601 strings as datetimes with parsedate::parse_iso_8601(), otherwise leave as a string. Partial datetimes are parsed as the earliest possible datetime, e.g. "2018" becomes "2018-01-01 UTC".

Examples

rr_apply_datatype("2014-04", "datetime")
#> [1] "2014-04-01 01:00:00 BST"
