Bad name for a data.frame. Fortunes, "dog" and all that.
Are you doing archeology? Given what you say next I wondered what  
range you were really asking for.
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.
