Hi r-helpers...
Why do I get this strange huge jump of 36524 days when changing "origin"
from 1969-01-01 to 1968-12-31. It should still be close to zero! This
really messes up my calculations of follow-up times in my analyses.
> julian(strptime("010169", format = "%d%m%y"),origin =
as.Date("1969-01-01"))
> Time difference of -0.04166667 days
> julian(strptime("311268", format = "%d%m%y"),origin =
as.Date("1968-12-31"))
> Time difference of 36524.96 days
Cheers,
Kare
