homogeneity | R Documentation |

Computes the homogeneity of a set of clusters given ground-truth classes, as defined in https://aclweb.org/anthology/D/D07/D07-1043.pdf

```
homogeneity(contingency, c, k)
```

`contingency` |
Table, contingency table between clusters and
conditions as returned by the |

`c` |
Vector of classes |

`k` |
Vector of clusters |

Numeric

```
clusters <- c(0, 0, 2, 1, 1, 0, 1)
classes <- c("A", "A", "A", "B", "B", "A", "B")
ct <- table(classes, clusters)
homogeneity(contingency = ct)
```
