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]] ______________________________________________ R-devel@r-project.org mailing list https://stat.ethz.ch/mailman/listinfo/r-devel
