### Description

This function displays a star coordinates plot introduced by Kondogan (2001).

### Usage

    starcoord(data, main = NULL, class = FALSE, outliers, vars = 0,
    scale = 1, cex = 0.8, lwd = 0.25, lty = par("lty"))

### Arguments

`data` | The dataset
`main` | The title of the plot
`class` | The class
`outliers` | instances to be highlighted as potential outliers
`vars` | variable to be scaled
`scale` | The scale factor
`cex` | A numerical value giving the amount by which plotting text and symbols should be scaled.
`lwd` | the width of the lines representing the axis
`lty` | The type of the lines representing the axis
