Checks that the input contains UK postcodes.

severity = getOption("assertive.severity", "stop"))
assert_any_are_uk_postcodes(x, na_ignore = FALSE,
severity = getOption("assertive.severity", "stop"))
is_uk_postcode(x)
|
x |
Input to check. |
na_ignore |
A logical value. If |
severity |
How severe should the consequences of the assertion be?
Either |
is_uk_postcode
returns TRUE
if the input string
contains a valid UK postcode. The assert_* function returns nothing but
throws an error when the is_*
function returns FALSE
.
The function doesn't guarantee that the postcode actually exists. It
should correctly return TRUE
for genuine postcodes, and will weed out
most badly formatted strings and non-existent areas, but some non-existent
districts may incorrectly return TRUE
. If you need 100
check against an up-to-date postcode database.
