## Cassini: A 2 Dimensional Problem

### Description

The inputs of the cassini problem are uniformly distributed on a `2`-dimensional space within 3 structures. The 2 external structures (classes) are banana-shaped structures and in between them, the middle structure (class) is a circle.

### Usage

    mlbench.cassini(n, relsize=c(2,2,1))

### Arguments

`n` | number of patterns to create
`relsize` | relative size of the classes (vector of length 3)

### Value

Returns an object of class `"mlbench.cassini"` with components

`x` | input values
`classes` | vector of length `n` with target classes
