    Histogram the occurrences of values returned by a function applied to RDD rows

    Histogram the occurrences of values returned by a function applied to RDD rows

    U

    The return type of the function

    f

    The function to apply to each RDD row

    normalized

    When true, histogram counts are normalized to sum to 1

    cumulative

    When true, histogram counts are cumulative

    returns

    A sequence ((u0, n0), (u1, n1), ...), sorted in decreasing order of counts nj

    Note

    When both cumulative and normalized are true, "counts" are analoglous to a sampled CDF
