big_number: Abbreviate large numbers by order of magnitude

In camille-s/camiller: Lots of convenience functions

Description

This picks out the order of magnitude of each number in a vector and returns a formatted abbreviation, such as 1230 –> 1.2k. It handles abbreviations through the trillions; after that, it's suggested that you switch over to scientific notation. The convenience of this function over those from the scales package is that you can mix & match orders of magnitude.

Usage

big_number(x, digits = 2)

big_money(x, digits = 2, currency = "$")

Arguments

x	A numeric vector
digits	Number of digits (significant figures) to keep; defaults to 2
currency	Symbol to use to denote currency; defaults "$"

Details

Its sibling big_money tacks on a currency symbol, placed after a negative sign if applicable.

Value

A character vector

Examples

big_number(c(123, 12345, 1234567), digits = 3)
big_number(c(-12000, 15000, 16000, 77777))
big_money(c(-12000, 15000, 16000, 2e6))
