[R] difference between 2 dates: IN MONTHS the way Mothers compute it

Hi R-people:  

I need a function to compute the number of months between 2 dates, in the same way a mother would do it.  

For example, if a kid is born on February 6, the number of months between that date and March 7 is exactly 1 month, although it is only 29 days.  

Thank you!
