Scale a vector or matrix of numbers into a new range.

1 | ```
rescale(x,newrange)
``` |

`x` |
A numeric vector, matrix or data frame. |

`newrange` |
The minimum and maximum value of the range into which x will be scaled. |

rescale performs a simple linear conversion of x into the range specified by newrange. Only numeric vectors, matrices or data frames with some variation will be accepted. NAs are now preserved - formerly the function would fail.

On success, the rescaled object, otherwise the original object.
