Support for the Date class

[adamryczkowski]

I'd like to include tagged missings (NAs) in the Date variable. But when I do the following

x <- rep(c(1,2),5)
x[[4]] <- tagged_na('a')
y <- as.Date(x, origin = '1992-01-01')
class(y)
#[1] "Date"
labelled(y, c("NA"=tagged_na('a')))
#Error: 'y' must be a numeric or a character vector

Is this behavior by design, or do I write a valid feature request? :-)

By design (and following the haven package), the labelled class could be apply only to numeric or character vector mut not to date.

Here, you are also mixing value labels and tagged_na which are two different systems. I guess you could use tagged_na with a date:

y <- as.Date(x, origin = '1992-01-01')
y[is.na(y)] <- tagged_na("a")

but you should refer to haven package documentation.
