Number options

Description

Control the settings for formatting numbers globally.

Usage

number_options(
  decimal.mark = ".",
  big.mark = " ",
  style_positive = c("none", "plus", "space"),
  style_negative = c("hyphen", "minus", "parens"),
  currency.prefix = "$",
  currency.suffix = "",
  currency.decimal.mark = decimal.mark,
  currency.big.mark = setdiff(c(".", ","), currency.decimal.mark)[1],
  ordinal.rules = ordinal_english()
)

Arguments

decimal.mark	The character to be used to indicate the numeric decimal point. The default (NULL) retrieves the setting from the number options.
big.mark	Character used between every 3 digits to separate thousands. The default (NULL) retrieves the setting from the number options.
style_positive	A string that determines the style of positive numbers: "none" (the default): no change, e.g. 1. "plus": preceded by +, e.g. +1. "space": preceded by a Unicode "figure space", i.e., a space equally as wide as a number or +. Compared to "none", adding a figure space can ensure numbers remain properly aligned when they are left- or right-justified. The default (NULL) retrieves the setting from the number options.
style_negative	A string that determines the style of negative numbers: "hyphen" (the default): preceded by a standard hyphen -, e.g. -1. "minus", uses a proper Unicode minus symbol. This is a typographical nicety that ensures - aligns with the horizontal bar of the the horizontal bar of +. "parens", wrapped in parentheses, e.g. (1). The default (NULL) retrieves the setting from the number options.
currency.prefix, currency.suffix, currency.decimal.mark, currency.big.mark	Settings for label_currency() passed on without the currency.-prefix.
ordinal.rules	Setting for label_ordinal() passed on without the ordinal.-prefix.

Value

The old options invisibly

Examples

# Default number formatting
x <- c(0.1, 1, 1000)
label_number()(x)

# Now again with new options set
number_options(style_positive = "plus", decimal.mark = ",")
label_number()(x)

# The options are the argument names with a 'scales.'-prefix
options("scales.style_positive")

# Resetting the options to their defaults
number_options()
label_number()(x)
