Convert integer to class Date
date, r, r-faq
Solution
`as.character()` would be the general way rather than use `paste()` for its side effect
> v <- 20081101
> date <- as.Date(as.character(v), format = "%Y%m%d")
> date
[1] "2008-11-01"
(I presume this is a simple example and something like this:
`v <- "20081101"`
isn't possible?)
Problem
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" ```
