Description

Converts the mid-point x-values and mean densities of binned data into (x,y)-coordinates of a histogram.

Usage

histcoord(x, y, yleft = 0, yright = 0)

Value

(2n+2)-by-2 matrix of (x,y)-coordinates to draw histogram as a connected line

Arguments

x

n-vector giving the bin mid-points

y

n-vector giving bin values

yleft

optional value specifying the value at the left edge

yright

optional value specifying the value at the right edge
