Helper functions for auto.shading. Given a variable to be mapped, a number of classes and possibly some more params, returns a list of break values. There should be one less break value than the number of classes.
quantileCuts(x, n = 5, params = NA)
sdCuts(x, n = 5, params = NA)
rangeCuts(x, n = 5, params = NA)An ordered list of the break values between classes
The variable to be mapped.
The number of classes.
Extra params for individual cut functions.
