even_lims: Set Even Limits Based on Data Values

In ryan-heslin/matador: Linear Algebra Visualization

Description

This function takes a numeric vector and returns a range of the negative and positive of the element with the highest absolute value. The lower bound is rounded down to the next integer, the upper bound rounded up. It is intended to set even limits on plots when called on the breaks or data values corresponding to an aesthetic, and usefully always returns an interval containing 0.

Usage

even_lims(vec)
