Dear R-help,
I am working on a R package for public health surveillance where the ISO
8601 representation of dates is of importance. Especially, the ISO Week
and ISO Year of a date needs to be extracted. I was quite happy to find
all of this implemented in the "Date" class with appropriate calls to
strptime/format (using e.g. %G and %V).
However, only later I realized that this functionality is currently not
implemented on Windows (I'm a happy Mac/Linux user). As this seriously
limits the applicability, I would like to enquire, if there are any plans
to make this functionality available in Windows as well? Or are there any
good workarounds to make
> format.Date("2001-12-31", "%G")
give "2002" instead of "" on Windows?
Best regards,
Michael Höhle
