## toydata2: Labelled Data for 3 Clusters

### Description

Artificially generated data on the 2 dimensional torus

### Usage

```
toydata2
```

### Format

This `data.frame`

contains the following components:

`phi`

column for the first angle

`psi`

column for the second angle

`label`

column for the clustering membership

### Details

toydata2 is an artificial data generated from a mixture of 3 clusters, where the first cluster is sampled from a spherical normal distribution, the second cluster is from the uniform distribution on a large āLā-shaped region, and the third cluster of size 50 is sampled from the uniform distribution on the entire 2-dimensional torus.
