The fmt_currency()
function lets us format numeric values as currencies.
The table generated by the info_currencies()
function provides a quick
reference to all the available currencies. The currency identifiers are
provided (name, 3-letter currency code, and 3-digit currency code) along with
the each currency's exponent value (number of digits of the currency
subunits). A formatted example is provided (based on the value of 49.95
) to
demonstrate the default formatting of each currency.
Usage
info_currencies(type = c("code", "symbol"), begins_with = NULL)
Arguments
- type
Type of currency
singl-kw:[code|symbol]
--- default:"code"
The type of currency information provided. Can either be
code
where currency information corresponding to 3-letter currency codes is provided, orsymbol
where currency info for common currency names (e.g., dollar, pound, yen, etc.) is returned.- begins_with
Show currencies beginning with a specific letter
scalar<character>
--- default:NULL
(optional
)Providing a single letter will filter currencies to only those that begin with that letter in their currency code. The default (
NULL
) will produce a table with all currencies displayed. This option only constrains the information table wheretype == "code"
.
Details
There are 172 currencies, which can lead to a verbose display table. To make
this presentation more focused on retrieval, we can provide an initial letter
corresponding to the 3-letter currency code to begins_with
. This will
filter currencies in the info table to just the set beginning with the
supplied letter.
Examples

begins with an "h"
