joyPlot: Display a series of density curves.

In plotrix/plotrix: Various Plotting Functions

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)

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.

Value

  xlab="Position",xlim=c(0,100))
 xlist<-list(first=xdens1,second=xdens2,third=xdens3)
 joyPlot(xlist,main="joyPlot with polygons",xlab="Position",
  fill=c("#ffcccc","#ccffcc","#ccccff"),xlim=c(0,100))
 joyPlot(xlist,main="joyPlot with overlapping polygons",
  fill=c("#ffcccc","#ccffcc","#ccccff"),xlim=c(0,100),
  newrange=c(0,1.5),xlab="Position")
