as.Date without "origin"
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 the documentation to match the new behavior.

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, which gives: origin aDateobject, or something which can be coerced byas.Date(origin, ...)to such an object. And: as.Datewill accept numeric data (the number of days since an epoch), butonlyiforiginis supplied. The behavior described in the help file and implemented in previous versions seems more reasonable than returning a date with an arbitrary "origin". In any case, in the r-devel there is a mismatch between the function and its description. -Dan [[alternative HTML version deleted]]
