search for: as_dat

dear members, I want to convert "12 APR 2023" into a Date object. I tried as_Date() from lubridate, but it is not working: > as_date("12 APR 2023") [1] NA Warning message: All formats failed to parse. No formats found. > as_date("12-APR-2023") [1] NA Warning message: All formats failed to parse. No formats found. I am looking for a shorthand way of d...

In the following example, the date class shows Inf as NA > as_date(Inf, origin = '1970-01-01') [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.

...though the internal storage is still a Date class object.

I don't think there's much wrong with is.na(as_date(Inf, origin='1970-01-01'))==FALSE, as there still is some "non-NA-ness" about the value (as difftime shows), but that the output when printing is confusing. The way cat is treating it is clearer: it does print Inf. So would this be a solution? format.Date <- function (x, ......

Indeed. as_date is from lubridate, but the same holds for as.Date. The output and it's interpretation should be consistent, otherwise it leads to confusion when programming.

...date for an infinite value, but given that this will have implications in other areas, there is a possibility of breaking code and it should be investigated a bit further imho.
