How to convert dd/mm/yy to yyyy-mm-dd in R
Solution 1:
Use lubridate package
library(lubridate)
dmy("27/06/16")
Solution 2:
With base R
as.Date(as.character("27/06/16"), format = "%d/%m/%y")
Solution 3:
One option would be to convert both date formats into a common POSIX representation:
d1 <- strptime("27/06/16", "%d/%m/%y")
d2 <- strptime("2016-06-27", "%Y-%m-%d")
Since both d1 and d2 should be of the same R class, you can then just compare them as you wish.
