Something like this should work, only Sept has 30 days, not 31:
> files <- seq(as.Date('2008-09-30'), by = '1 day', length = 250)
> input <- paste(".....jsp?y="
+ , format(files, "%Y")
+ , "&m="
+ , format(files, "%m")
+ , "&d="
+ , format(files, "%d")
+ , sep = ""
+ )
>
> head(input)
[1] ".....jsp?y=2008&m=09&d=30" ".....jsp?y=2008&m=10&d=01"
[3] ".....jsp?y=2008&m=10&d=02" ".....jsp?y=2008&m=10&d=03"
[5] ".....jsp?y=2008&m=10&d=04" ".....jsp?y=2008&m=10&d=05"
