[R] Selecting data based on the range of dates

[Belle]

Hi:

I want to give an index with all the dates between Sept. to Nov. as 1, and
anything else is 0. It doesn't matter which year it is, as long as it is
between Sept. to Nov, then set up to 1, otherwise is 0.

My data frame looks like below:

ID	Date
201	1/1/05 6:07 AM
201	3/27/09 9:45 AM
201	9/29/09 8:44 AM
203	10/16/08 10:01 AM
203	10/28/08 9:45 AM
203	10/31/08 11:12 AM
203	11/7/08 11:32 AM
203	11/14/08 10:30 AM
203	11/19/08 10:40 AM
203	11/25/08 3:25 PM
203	12/4/08 10:48 AM
203	1/28/09 11:04 AM
203	2/12/09 3:15 PM
203	2/16/09 2:59 PM
203	2/24/09 2:45 PM
203	3/4/09 10:14 AM
203	3/27/09 11:36 AM
203	4/1/09 10:43 AM
203	4/16/09 2:28 PM
203	4/22/09 2:37 PM
203	4/29/09 10:48 AM
203	4/1/09 10:45 AM
203	12/3/09 9:07 AM
203	12/11/09 8:58 AM
203	1/7/10 8:53 AM

Thanks
