[Rd] seq.Date bug?

R> seq(as.Date(Sys.Date()), by="-1 months", length=6) [1] "2012-01-31" "2011-12-31" "2011-12-01" "2011-10-31" "2011-10-01" "2011-08-31" R>

Notice how October appears twice.

Now, date arithmetic is gruesome but the documentation for seq.Date et al does not hint it wouldn't honour the by= argument. So a bug, or merely a somewhat less than desirable features.

(And yes, I think I know that Hadley's lubridate has code for this too, but so may my RcppBDT which is sitting on top of Boost::DateTime code ...)
