symmetric_limits: Symmetric limits

In ggstats: Extension to 'ggplot2' for Plotting Stats

Symmetric limits

Description

Expand scale limits to make them symmetric around zero. Can be passed as argument to parameter limits of continuous scales from packages {ggplot2} or {scales}. Can be also used to obtain an enclosing symmetric range for numeric vectors.

Usage

symmetric_limits(x)

Arguments

x	a vector of numeric values, possibly a range, from which to compute enclosing range

Value

A numeric vector of length two with the new limits, which are always such that the absolute value of upper and lower limits is the same.
