quant_bin_1d: One-Dimensional Empirical Quantile Binning
In kmaurer/iqbin: Iterative Quantile Binning

used for binning the numeric values by empirical quantile

1	quant_bin_1d(xs, nbin, output = "data", jit = 0)

`xs`	Numeric vector of values to be binned
`nbin`	An integer defining the number of bins to partion the xs into
`output`	Output Structure: "data" for just the binned data,"definition" for a list of bin centers and boundaries, or "both" for list containing both data and definition
`jit`	non-negative value to specify a random uniform jitter to the observed values prior to partitioning by quantiles.
