hi everybody,
is this intended behaviour?
> x <- as.Date('0-01-01')
> as.Date(as.character(x))
[1] "0-01-01"
> a <- x - 365
> as.Date(a)
[1] "-1-01-01"
> as.Date(as.character(a))
Error in charToDate(x) :
character string is not in a standard unambiguous format
Is this a bug?
I found this, while trying to convert dates stored as
"months since -2-01-01 00:00:00".
For the past I extracted this first_date string and converted my data
using
dates <- as.Date(x, origin=as.Date(first_date))
But this fails with -2-01-01
Any ideas how to solve this?
thanks and best regards,
Stefan
