`select.range`

accepts two vectors of paired observations and
returns a vector of observations from `data`

. The observations
returned are those for which the paired values in `groupvec`

are
within the range specified by `min`

and `max`

.
NOTE: The in-range condition is *greater than or equal to* `min`

and *less than* `max`

. This allows contiguous ranges to be
specified without returning the same value in two sets.

1 | ```
select.range(data, groupvec, min, max)
``` |

`groupvec` |
A vector of observations to be used for grouping. |

`min` |
The minimum value of the range. |

`max` |
The maximum value of the range. |

`data` |
A numeric vector of observations. |

The subset of observations from `data`

is returned invisibly.
