Overlapping Density Plots - obsolete

Description

Densities for two independent samples are estimated and plotted.

Usage

overlap.density(x0, x1, ratio=c(0.05, 20), compare.numbers=TRUE, 
plotit=TRUE, gpnames=c("Control", "Treatment"), xlab="Score")

Arguments

x0 control group measurements
x1 treatment group measurements
ratio the range within which the relative numbers of observations from the two groups are required to lie. [The relative numbers at any point are estimated from (density1*n1)/(density0*x0)]
compare.numbers If TRUE (default), then density plots are scaled to have total area equal to the sample size; otherwise total area under each density is 1
plotit If TRUE, a plot is produced
gpnames Names of the two samples
xlab Label for x-axis
