Change dates to first day of the month in R

Question

How do I change my dates to the first day of the month...so 3/31/19 becomes 3/1/19, 2/28/19 becomes 2/1/19, and so on.

Thanks

Try `lubridate::floor_date`: e.g. `lubridate::floor_date(Sys.Date(), unit = "month")` — dave-edison, Mar 06 '19 at 21:48

@thelatemail Yup I realised, thanks. Added your dupe link. There are *a lot* of closely related questions, all of which would've been useful and relevant to OP. — Maurits Evers, Mar 06 '19 at 22:01

One of the many ways to do it is to use lubridate package.

library(lubridate)
date <- dmy('11/02/2019')
day(date) <- 1
date
