Error: object 'as_date' not found
Must be from some not-named package...
But don't confuse the format of an object when printed with its underlying
value:
> as.Date(Inf,origin = '1970-01-01')
[1] NA
> str(as.Date(Inf,origin = '1970-01-01'))
Date[1:1], format: NA
> as.numeric(as.Date(Inf,origin = '1970-01-01'))
[1] Inf
> is.na(Inf)
[1] FALSE
> is.na(as.Date(Inf,origin = '1970-01-01'))
[1] FALSE
> str(as.Date(27,origin = '1970-01-01'))
Date[1:1], format: "1970-01-28"
> as.numeric(as.Date(27,origin = '1970-01-01'))
[1] 27

In the following example, the date class shows Inf as NA

[1] NA
This is misleading as is.na() reports incorrectly
> is.na(as_date(Inf, origin = '1970-01-01'))
[1] FALSE
The correct approach here would probably to have an Inf (and -Inf)
*displayed* rather than NA.
