Checking dates for entry errors
Hello Everyone,
?
I have a question about how best to check dates for?entry errors. I recently discovered that R will read?the incorrectly entered date "11/23/21931" without producing a warning or an?error message at least under some circumstances.
?
> as.Date("11/23/21931", format = "%m/%d/%Y")
[1] "2193-11-23"
> as.Date("21931-11-23")
