Checks if two vectors or two data frames are from the same equivalence class

```
is.equivalent(x, y, tollerance = .Machine$double.eps^0.5)
```

`x` |
either a numeric vector, or a data.frame containing such vectors. |

`y` |
either a numeric vector, or a data.frame containing such vectors. |

`tollerance` |
numeric >= 0. Differences smaller than tolerance are not considered. |

logical TRUE if the two vectors are from the same equivalence class.
