ash: Average Shifted Histograms From a Histogram.

In HistogramTools: Utility Functions for R Histograms

Description

Computes a univariate average shifted histogram (polynomial kernel) given a single input histogram.

Usage

HistToASH(h, m=5, kopt=c(2,2))

Arguments

h	A histogram object (created by hist) representing a pre-binned dataset.
m	optional integer smoothing parameter, passed to ash1().
kopt	vector of length 2 specifying the kernel, passed to ash1().

Details

This function takes a histogram and uses the counts as the input to the ash1() function in the ash package to compute the average shifted histogram.
