In R, how do I output a lubridate compatible date in yyyymmdd format? The equivalent of .ToString("yyyyMMdd") in .NET?

Question

In R, I can parse a date into Lubridate format using:

d <- ymd("2013-02-15")

How do I output this in yyyyMMdd format, e.g.:

20130215

The equivalent .NET command would be:

.ToString("yyyyMMdd")

I know the answer to this will be simple, but I've spent the last hour attempting to find any reference to outputting dates with Lubridate with no success so far.

Answer 1

format(d, "%Y%m%d")

yields

> format(d, "%Y%m%d")
[1] "20130215"
