Is it a tag set (a delimited multi-value field)?

Source: R/dt-serialized.R
is_tags.Rd

Tests whether each value is a flat set of short members joined by ; or | — the shape a multi-select / "tags" column takes once a list is collapsed to a string ("Volunteer;Donor;Board", "a|b|c"). Requires a ;/| delimiter and at least two non-empty, reasonably short members, so ordinary prose or single values do not match. (Comma is intentionally excluded — it is too common in numbers, names and sentences to be a reliable set delimiter.)

Usage

is_tags(x)

Arguments

x

A character vector.

Value

Logical vector; TRUE for a delimited set of 2+ members, FALSE otherwise, NA where x is NA.

Examples

#> [1]  TRUE  TRUE FALSE FALSE    NA
#> TRUE TRUE FALSE FALSE NA
