Function for normalizing the range of values of a continuous variable using a linear scaling within the range of the variable.

1 | ```
LinearScaling(x, mx = max(x, na.rm = T), mn = min(x, na.rm = T))
``` |

`x` |
A vector with numeric values |

`mx` |
The maximum value of the continuous variable being normalized
(defaults to the maximum of the values in |

`mn` |
The minimum value of the continuous variable being normalized
(defaults to the minimum of the values in |

The linear scaling normalization consist in transforming the value x into

(x - MIN) / (MAX - MIN)

An object with the same dimensions as `x`

but with the values normalized
