I have an integer which I want to convert to class Date
. I assume I first need to convert it to a string, but how?
My attempt:
v <- 20081101
date <- as.Date(v, format("%Y%m%d"))
Error in charToDate(x) : character string is not in a standard unambiguous format
Using paste()
works, but is that really the correct way to do the conversion?
date <- as.Date(paste(v), format("%Y%m%d"))
date
[1] "2008-11-01"
class(date)
# [1] "Date"
You can use ymd
from lubridate
lubridate::ymd(v)
#[1] "2008-11-01"
Or anytime::anydate
anytime::anydate(v)
#[1] "2008-11-01"
Another way to get the same result:
date <- strptime(v,format="%Y%m%d")
