search for: as_date

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 do...

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. I understand that the difference exists after asking a question on Stack Overflow: https://stackoverflow.com/q/50766089/914686 This un...

...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.
