This is a simple function to convert a proportion gain over one time interval to a proportion gain over a different time interval. For example, you can use this function to figure out that a stock gain of 0.08 (8%) over 70 trading days corresponds to an annualized (i.e. 252-day) gain of 0.319 (31.9%).

`rate` |
Numeric value (or vector) representing the growth rate of an investment over a
period of |

`units.in` |
Number of time units over which the investment had a growth rate of |

`units.out` |
Number of time units you would like to calculate a growth rate for. |

Numeric value (or vector) indicating the proportion gain over `units.out`

time units.
