window_intersect: window_intersect
In dfeehan/dhstools: Tools for analyzing Demographic and Health Surveys (DHS)

Description Usage Arguments Details Value

given two intervals, figure out the intersection between the first and the second

NOTE that the intervals are treated as half-open (start,finish] so that an event that happens exactly at time b is counted in (a,b] but not in (b, c]

1	window_intersect(a, b)

`a`	the first window; here, we use all three components (start, finish, event)
`b`	the second window; here, we only use the start and finish time, and ignore any events

TODO - should write a more detailed description

a window containing the exposure and events from a that takes place during the time given by b; also, if a has an event and it takes place during b, it is included
