How do I convert day-of-year to date? For example, what's the date for 104th day of 2004?

This is the opposite of How do you convert POSIX date to day of year in R?

I found that @TMS answer ignores the year specified in the origin, replacing it with the actual year you are executing the command (as @Shekeine found). Doing this seems to work fine though:

as.Date(104, origin = "2014-01-01")

CAUTION: day-of-year is zero based in this case!
