How to convert dd/mm/yy to yyyy-mm-dd in R

Question

I have a vector with dates values in this format dd/mm/yy e.g.(27/06/16). I want to convert this in this format yyyy-mm-dd e.g.(2016-06-27) for logical comparison. I am using this expression:

as.Date(as.character("27/06/16"), format = "%d")

and output comes out as:

"2016-07-27"

How can I convert this into required format.

Use lubridate package

library(lubridate)
