How to delete observations with a date that is outside a week of another week

[eclaire]

Hello, I need to delete observations that have an activity session outside of 1 week from admit or discharge.  My data look like the following:

(ID=subject, adate= admission date, ddate= discharge date, actdate= activity session date)

ID   adate        ddate          actdate

1    1/3/2021   1/30/2021   1/11/2021

1    1/3/2021   1/30/2021   1/9/2021

2    1/4/2021   1/29/2021   1/28/2021

2    1/4/2021   1/29/2021   1/15/2021

What I want:

ID   adate        ddate        actdate

1    1/3/2021   1/30/2021   1/9/2021

2    1/4/2021   1/29/2021   1/28/2021

Thank you!

No observation satisfies your condition, as in all either the adate or the ddate are more than one week from actdate.

Or did you mean: actdate must be between one week before adate and one week after ddate?
