Converting Integers to Date in R

Question

I want to convert my integer column to Date. the integer number looks like this (20160101). When using the as.Date function and by typing the origin argument to be \"2016-01

Answer 1

just for your interest an alternative approach using lubridate and just keeping month and day.

tmp <- as.integer(x = 20160101) tmp %>% lubridate::ymd() %>% format("%m-%d")

Please notice, that you will be left with just a string afterwards.

tmp %>% lubridate::ymd() %>% format("%m-%d") %>% is.Date()

Is going to be FALSE. Without the cutoff of the year it will be TRUE. So to keep the date format, like Tim mentioned, an alternative lubridate approach would be:

 tmp %>% lubridate::ymd()
