View source: R/simple.densityplot.R

Description

Allows one to compare empirical densities of different distributions in a simple manner. The density is used as graphs with multiple histograms are too crowded. The usage is similar to side-by-side boxplots.

Usage

1

Arguments

x

x may be a sequence of data vectors (eg. x,y,z), a data frame with numeric column vectors or a model formula

...

You can pass in a bandwidth argument such as bw="SJ". See density for details. A legend will be placed for you automatically. To overide the positioning set do.legend="manual". To skip the legend, set do.legend=FALSE.

Value

Makes a plot

Basically a modified boxplot function. As well it should be as it serves the same utility: comparing distributions.

mat <- cbind(Uni05 = (1:100)/21, Norm = rnorm(100),
             T5 = rt(100, df = 5), Gam2 = rgamma(100, shape = 2))
simple.densityplot(data.frame(mat))
