drawSplitDensity: Draw a Split Density Plot

In oaPlots: OpenAnalytics Plots Package

Description

Draw a Split Density Plot

Usage

drawSplitDensity(x = NULL, y = NULL, densityObj = NULL, yshift = 0,
  colVec, outerCol, lwd = 2, split = NULL, yScale = NULL,
  fillBackground = FALSE)

Arguments

x	x vector from a density object. e.g. data <- rnorm(100); x <- density(data)$x
y	y vector from a density object
densityObj	an object created by the function density()
yshift	vertical shift to be applied to the y object
colVec	color vector for the shaded regions that compose the interior of the plot. The length of 'colVec' should be one greater than the length of split
outerCol	the color for the outer density line
lwd	line width for the outer density line
split	vector of x values at which to split the density plot
yScale	vertical scale at which to plot the density. For example, a call with 'yScale = 1' will produce a density curve scaled between 0 and 1
fillBackground	binary specification of whether to fill in the background the outerCol color

Value

none. Graph is plotted to the current device

Examples

library(RColorBrewer)
data <- rnorm(1000)
x <- density(data)$x
y <- density(data)$y
colVec <- brewer.pal(9, "Blues")[3:8]
outerCol <- brewer.pal(9, "Blues")[9]

oaTemplate(xlim = range(x), ylim = c(0, 1), ygrid = 0, cex.axis = 1.2)
drawSplitDensity(x, y, colVec = colVec, split = c(-8),
		outerCol = outerCol,
		yScale = 0.95, yshift = 0)
