Seems like it makes sense to have a default origin of 1970-01-01 for
as.Date.numeric(). Are there any strong arguments for requiring users
to specify the origin for every invocation of as.Date.numeric()?
The code could be:
as.Date.numeric - function(x, origin=1970-01-01, ...)
{
if ((missing(origin) nargs()==1)
|| (is.character(origin) origin==1970-01-01 nargs()==2))
return(structure(as.integer(x), class=Date))
as.Date(origin, ...) + as.integer(x)
}
I guess the use of as.integer(x) is debatable, but using it seems
consistent with the Details section of ?Date.

R-devel,
I would like to second Gabor Grothendieck's request from September (
http://www.nabble.com/as.Date.numeric-to12962733.html#a12962733 )
on adding a default value (1970-01-01) to the origin argument of
as.Date.numeric.
I realize there is good reason to allow for origin to be specified,
but I don't see why it must be up to the user at each and every
invocation if most (if not all) users will simply be using 1970-01-01.
My first contact was building quantmod for CRAN - many more hidden
errors occur as I test on R-devel. It just seems to me to be an easy
compromise to what will undoubtedly cost many hours of debugging
across all packages/users.
Thank you for your consideration,
Jeff Ryan
