number

A low-level numeric formatter

Description

This function is a low-level helper that powers many of the labelling functions. You should generally not need to call it directly unless you are creating your own labelling function.

Usage

number(
  x,
  accuracy = NULL,
  scale = 1,
  prefix = "",
  suffix = "",
  big.mark = " ",
  decimal.mark = ".",
  trim = TRUE,
  ...
)

Arguments

`x`	A numeric vector to format.
`accuracy`	A number to round to. Use (e.g.) `0.01` to show 2 decimal places of precision. If `NULL`, the default, uses a heuristic that should ensure breaks have the minimum number of digits needed to show the difference between adjacent values. Applied to rescaled data.
`scale`	A scaling factor: `x` will be multiplied by `scale` before formating. This is useful if the underlying data is very small or very large.
`prefix`	Symbols to display before and after value.
`suffix`	Symbols to display before and after value.
`big.mark`	Character used between every 3 digits to separate thousands.
`decimal.mark`	The character to be used to indicate the numeric decimal point.
`trim`	Logical, if `FALSE`, values are right-justified to a common width (see `base::format()`).
`...`	Other arguments passed on to `base::format()`.

Value

A character vector of length(x).
