Did you mean

d <- strptime(ddd, "%Y%m%d")

up there?  ccc is the form that has the hyphens.

Using ddd works for me:

> format(Sys.time(), "%H:%M:%OS3")
[1] "15:31:10.113"
> ddd <- c("20110407", "19891012")
> strptime(ddd, "%Y%m%d")
[1] "2011-04-07" "1989-10-12"

and ?strptime clearly shows an example without separators.
