OptionalhighBias towards larger units. Default 1.5. Must be finite and non-negative (as in R).
OptionalminMinimal number of intervals. Default n / 3 rounded down (computed from n before it is truncated). Truncated
towards 0 to an integer (as in R); NaN, a negative value or one greater than n is an error.
OptionalnDesired number of intervals. Default 5. Truncated towards 0 to an integer (as in R); NaN, a negative value
or one of 2^31 or more in absolute value is an error (unless x has no finite values).
OptionalshrinkFactor applied to the cell when the range is very small. Default 0.75. Must be finite and positive (as in R).
Optionalu5Bias towards 5 over 2 times a power of 10. Default 0.5 + 1.5 * highUBias. Must be finite and non-negative (as
in R).
