Convert numeric to date

Question

I\'d like to convert this type of numeric values to a date but it doesn\'t work.

20100727 for instance

I tried to convert the numeric to charact

Answer 1

If it is a numeric value, 20100727, as.Date requires it to be first converted to string, or else, would have issue

as.Date(20100727, "%Y%m%d")

Error in charToDate(x) : character string is not in a standard unambiguous format

---

anydate from anytime can internally do this conversion

library(anytime)
date1 <- anydate(20100727)
date1
#[1] "2010-07-27"
str(date1)
#Date[1:1], format: "2010-07-27"

Also, takes the character string as input

anydate("20100727")
#[1] "2010-07-27"
