cp_breaks: Calculate Map Breaks
In chris-prener/prener: Chris Prener's R Functions

This function wraps the process I have been using to construction data classes for choropleth maps using ggplot2.

1	cp_breaks(.data, var, newvar, classes, style, clean_labels = TRUE)

`.data`	A tbl or sf object
`var`	The existing variable to create classes of
`newvar`	The new variable for storing the factor data
`classes`	The number of breaks or classes to create
`style`	The method for calculating classes, see classInt::classIntervals
`clean_labels`	A logical scalar; if `TRUE`, the comma will be converted to a dash and the parantheses and brackets will be removed
