simple.densityplot {UsingR} | R Documentation

## Plots densities of data

### 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

    simple.densityplot(x, ...)

### 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

### Author(s)

### References

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

### Examples

    ## taken from boxplot
    ## using a formula
    data(InsectSprays)
    simple.densityplot(count ~ spray, data = InsectSprays)
    ## on a matrix (data frame)
    mat <- cbind(Uni05 = (1:100)/21, Norm = rnorm(100),
                 T5 = rt(100, df = 5), Gam2 = rgamma(100, shape = 2))
    simple.densityplot(data.frame(mat))
