The new (2022-10-11 r83083 ucrt) as.Date function returns a date rather than an
error when called without "origin" specified.
# previous versions of R
as.Date(0)
# Error in as.Date.numeric(0) : 'origin' must be supplied
# new:
as.Date(0)
# [1] "1970-01-01"
This is at odds with the help file, wh
I've felt that "as.Date" should default to origin "1970-01-01", so I
added a modification to Ecfun:
Ecfun::as.Date1970(0)
If R-devel chose to change the default on this, I would happily
deprecate Ecfun::as.Date1970 in favor of base::as.Date ;-)
I would therefore support changing
I don't see a compelling rationale for changing the default behavior as.Date to
deviate from the wholly reasonable status quo of "as.Date will accept numeric
data (the number of days since an epoch), but only if origin is supplied." That
has been the expectation for a long, long time.
In any c
This is in R-devel, mind you, i.e., unreleased and quite possibly unfinished
work.
No released version of R does this. E.g.,

> version

Of course. But the broken as.Date in R-devel breaks one of my packages, so I'm
getting threats of the package being removed from CRAN in a few days if the
breakage is not resolved.

Dear all,
I would throw in my vote to have origin = "1970-01-01" as a default in

In fact, as.numeric seems to not even have a method for class "Date", and so
