Quantlet:		cltobindata
Description:		Bins a classified data set cl with frequencies fr

Usage:	`{xb,yb,d,orig} = cltobin (gr, fr)`
Input:
	`gr`	m x 1 vector of interval bounds
	`fr`	(m-1) x 1 vector of frequencies corresponding to each interval of cl
Output:
	`xb`	n x 1 vector, the indices of the nonempty bin
	`yb`	n x 1 vector of frequencies corresponding bins of xb
	`d`	scalar - the binwidth of this equidistant grid
	`orig`	scalar - the origin

Note:

The gr vector represents a grid (must be ordered ascendently) and the corresponding fr vector represents the numbers of observations in the corresponding intervals (given by gr vector). E.g., gr=#(1,2,3) and fr=#(7,4) represents the dataset containing 7 observations in the interval [1,2) and 4 observations in the interval [2,3). The representative for each interval is the mean of its boundaries.

Example:

library("xplore") x=aseq(2,10,3) y=#(1,6,4,3,15,10,9,4,5) cltobindata(x,y)
