Calculates the "center" quantiles, always including the median, when n is odd.
If the numeric variable has fewer than 6 unique observed values,
this will send the data to cutByTable. The default return
will find dividing points at three quantiles: c(0.25, 0.50, 0.75)
If n=4, the dividing points will be c(0.20, 0.40, 0.60, 0.80) If
n=5, c(0.0, 0.25, 0.50, 0.75, 1.0) Larger n that are odd will
include 0.5 and evenly spaced points out to proportions 0 and
1.0. Larger n that is even will return evenly spaced points
calculated by R's pretty function.
