plot.gains {gains}

Plotting Gains Table Objects

Description

Plot method for objects of class gains. These plots are sometimes called lift charts.

Usage

## S3 method for class 'gains'
plot(x, y=NULL, xlab="Depth of File", ylab="Mean Response", 
    type="b", col=c("red3","bisque4","blue4"), pch=c(1,1,1), lty=c(1,1,1),
    legend=c(
    "Mean Response","Cumulative Mean Response","Mean Predicted Response"),
    ylim=c(min(c(x$mean.resp,x$mean.prediction)),
    max(c(x$mean.resp,x$mean.prediction))), main="Gains Table Plot", ...)

Arguments

x

an object of class gains.

y

included for compatability with the plot generic but is not used.

xlab

a title for the x axis. See title.

ylab

a title for the y axis. See title.

type

what type of plot should be drawn. The default is "b" for points and lines.

col

vector of length 3 specifying the colors for the series of mean response rates, cumulative mean response rates, and mean predicted response rates, respectively.

pch

vector of length 3 specifying the plotting characters for the series of mean response rates, cumulative mean response rates, and mean predicted response rates, respectively.

lty

vector of length 3 specifying the line types for the series of mean response rates, cumulative mean response rates, and mean predicted response rates, respectively.

legend

character or expression vector of length 3 specifying the legend descriptions for the series of mean response rates, cumulative mean response rates, and mean predicted response rates, respectively.

ylim

the y limits of the plot. See plot.window.

main

an overall title for the plot. See title.
