Display a series of density curves.
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.
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)
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. |
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.
