violinplot {UsingR} | R Documentation

## Plots violinplots instead of boxplots

### Description

This function serves the same utility as side-by-side boxplots, only it provides more detail about the different distribution. It plots violinplots instead of boxplots. That is, instead of a box, it uses the density function to plot the density. For skewed distributions, the results look like "violins". Hence the name.

### Usage

    violinplot(x, ...)

### Arguments

`x` | Either a sequence of variable names, or a data frame, or a model formula
`...` | You can pass arguments to polygon with this. Notably, you can set the color to red with col='red', and a border color with border='blue'

### Value

Returns a plot.

This is really the boxplot function from R/base with some minor adjustments

### Examples

    ## make a "violin"
    x <- rnorm(100) ;x[101:150] <- rnorm(50,5)
    violinplot(x,col="brown")
    f<-factor(rep(1:5,30))
    ## make a quintet. Note also choice of bandwidth
    violinplot(x~f,col="brown",bw="SJ")
