Best way to do temporal joins in R?
I've been playing with zoo a bit, and it seems ok except it doesn't
support non-unique time stamps when performing joins. I have two
databases which contain a dataframe of a Date object (with the time, not
just MM/DD/YY), e.g.:
DB 1:
UniqueID,Date1,Data 1,Data 2
DB 2:
Date2, Station, Data 3
We'll say Station can contain three values: A,B and C
DB 1 may have some repeat times,
