Are you doing archeology? Given what you say next I wondered what
range you were really asking for.
The dates are in the format 20091114 so i'm just going to treat them
as
numbers for clean up purposes.
I know that i use subset but not sure how to proceed from there.
subdata <- subset(data, date_abandoned > "01010000"()
The problem with > "1010000" is that your specified minimum point had
an insufficient number of "places" to be in YYYYMMDD format.
