Is it a currency symbol + amount?

Source: R/dt-currency.R
is_currency_symbol.Rd

Tests whether each element is a currency symbol immediately followed by a numeric amount with at most two decimals, e.g. "$12.30", "€299.10", "¥1222", "£49.99". Recognised symbols are $, € (euro), ¥ (yen), and £ (pound).

Usage

is_currency_symbol(x)

Arguments

x

A character vector of candidate values.

Value

A logical vector the same length as x: TRUE where the value matches the symbol+amount pattern, FALSE otherwise, NA where x is NA.

Details

Rejects thousands separators ("$1,000"), more than two decimals ("$1.234"), and a bare symbol ("$"). Extend the character class in the regex to admit more symbols.
