plotrix (version 3.8-2)

joyPlot: Display a series of density curves.

Description

joyPlot displays a matrix of density curves or other two component lists whose names are x and y. The labels for each line/polygon are displayed on the left axis of the plot. The labels default to the names of the components of x if these are present.

Usage

joyPlot(x,mar=c(5,4,4,2),newrange=c(0,1),border=NA,fill=NULL,
 main="",xlab="",ylab="",xlim=NA,line_labels=names(x),xat=NULL,
 xaxlab=NULL)

Value

nil

Arguments

x

A list of density curves or other objects with x and y values.

mar

Margins for the plot.

newrange

Passed to rescale to scale the values to fit the bands on the plot. See Details.

border

The border colors for the polygons.

fill

Optional fill colors for the polygons.

main

Text for the title for the plot.

xlab,ylab

The x and y axis labels.

xlim

Optional limit for the x axis as density returns values outside the range of the values in x.

line_labels

Labels for the lines/polygons dieplayed.

xat

Optional custom x tick positions.

xaxlab

Optional custom x tick labels.

Details

The density curves or other x/y lists will be scaled so that the largest will fit into the one user unit band allocated for each curve by default. If the second value of newrange is changed, the heights of the curves will change proportionately. See the third exampls.
