Convert yyyymmdd string to Date class in R

Question

I would like to convert these dates with format YYYYMMDD to a Date class.

dates <- data.frame(Date = c(\"20130707\", \"20130706\", \"20130705\", \"2013070         


        

Answer 1

Use the lubridate package for an easy conversion:

date_test <- data.frame(Date = c("20130707", "20130706", "20130705", "20130704"))
date_test$Date <- ymd(date_test$Date)

date_test
        Date
1 2013-07-07
2 2013-07-06
3 2013-07-05
4 2013-07-04
