signs: Add plus signs or proper minus signs

In BenjaminWolfe/typewritr: An R package for oddball characters and common R Markdown tasks

Description

The true minus sign (UTF 2212) – neither an em dash, nor an en dash, nor the usual hyphen-minus – is highly underrated. It just makes everything look better! This function builds on the formatting functions from the scales package by replacing the hyphen-minus with a true minus, and adding a plus sign if desired.

Usage

signs(..., format = scales::number, plus_sign = FALSE)

Arguments

...	Numeric vector and any other arguments passed to format.
format	Function that formats a numeric vector, such as scales::number, scales::comma, scales::percent, or a function returned by scales::unit_format (all of which are documented at number_format).
plus_sign	Logical. Should positive values start with plus signs?

Value

A UTF-8 character vector

Examples

signs(seq(-5, 5))
signs(seq(-5, 5), plus_sign = TRUE)
signs(seq(-5, 5) / 100, format = scales::percent, plus_sign = TRUE)
