Merge three different columns into a date in R

Question

Right now, I am having 3 separate columns as year, month, and day in a data file in R. How do I merge these three columns into just one column and make R understand that it

Answer 1

Since your year, month and day types are numerical the best function to use is the make_date function from the lubridate package. The tidyverse style solution is therefore

library(tidyverse)
library(lubridate)

data %>%
  mutate(date = make_date(year, month, day))
