regressogram: Regressogram

Description

Computes and plots the regressogram for a single predictor and single response relationship. The regressogram is plotted using ggplot2.

Usage

regressogram(x, y, nbins = 10, show.bins = TRUE,
			       show.means = TRUE, show.lines = TRUE,
             x.lab = "X", y.lab = "Y", main = "TITLE")

Arguments

x

A vector of predictor values for the data. Must be the same length as y.

y

A vector of response values for the data. Must be the same length as x.

nbins

How many bins to use construction of the regressogram.

show.bins

A logical argument specifying if dashed vertical lines should be drawn at the boundaries of the bins. Default is TRUE.

show.means

A logical argument specifying if a large point should be overlayed at the midpoint of each bin and the respective mean of the response values within that bin. Default is TRUE.

show.lines

A logical argument specifying if a line should be drawn connecting the points determined by show.means. Default is TRUE.

x.lab

Label for the x-axis.

y.lab

Label for the y-axis.

main

Title for the regressogram.

Value

regressogram returns a plotted regressogram using the ggplot2 package.
