tidywikidatar (version 0.5.9)

tw_check_pid: Ensures that input appears to be a valid Wikidata property id (i.e. it starts with P and is followed only by digits)

Description

Mostly used internally by other functions.

Usage

tw_check_pid(property, logical_vector = FALSE, non_pid_as_NA = FALSE)

Value

A character vector with only strings appearing to be Wikidata identifiers; possibly shorter than input

Arguments

property

A character vector of one or more Wikidata property identifiers.

logical_vector

Logical, defaults to FALSE. If TRUE, returns a logical vector of the same length as input, where TRUE corresponds to seemingly meaningful property identifiers.

non_pid_as_NA

Logical, defaults to FALSE. If TRUE (and if logical_vector is set to FALSE), a vector of the same length is returned, with NA replacing items that are seemingly not meaningful property identifiers.

Examples

tw_check_pid(property = c("P19", "p20", "Not an property id", "20", NA, "Q5", ""))

tw_check_pid(
  property = c("P19", "p20", "Not an property id", "20", NA, "Q5", ""),
  logical_vector = TRUE
)

tw_check_pid(
  property = c("P19", "p20", "Not an property id", "20", NA, "Q5", ""),
  non_pid_as_NA = TRUE
)
