Check text against a naxp

Source: R/encode.R
naxp_accepts.Rd

naxp_accepts() says whether a naxp accepts each text, and naxp_canonical_form() gives the form each accepted text decodes to.

Usage

naxp_accepts(text, naxp)

naxp_canonical_form(text, naxp)

Arguments

text

A character vector.

naxp

A naxp from naxp_parse(), a pattern string or a naxp_encoded vector, whose naxp is used. For naxp_decode(), it is needed only where x is not a naxp_encoded vector.

Value

  • naxp_accepts(): a logical vector the same length as text, with its names. It is FALSE, never NA, for NA and for invalid text.

  • naxp_canonical_form(): a character vector the same length as text, with its names, holding NA for NA and for invalid text.

Details

Neither needs the text's encoded value, so both work for a naxp of any size.

Examples

nl_postcode <- naxp_parse(r"(\9\9\9\9 \s!! \A\A)")

naxp_accepts(c("1012AB", "1012 AB", "1012-AB"), nl_postcode)
#> [1]  TRUE  TRUE FALSE
naxp_canonical_form(c("1012AB", "1012 AB", "1012-AB"), nl_postcode)
#> [1] "1012 AB" "1012 AB" NA
