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.
