You can do this with

a <- seq(ISOdate(2001,1,1,tz="GMT"), ISOdate(2001,12,31,tz="GMT"),"days")
format(a, format="%m/%d/%Y", tz="GMT")

If you live in GMT then I think you can omit the tz. There may be an easier way
if you don't live in GMT, but I can't find it. The problem is getting ISOdate to
generate a time at midnight, so that format will automatically drop the time
from the date.
