getting ISO week

According to the definition in ?strptime (which is not the same as the
ISO definition):

format(x, "%W") returns

"Week of the year as decimal number (00?53) using Monday as the first
day of week (and typically with the first Monday of the year as day 1
of week 1). The UK convention."

The first day of 2008 is a Tuesday which means that 2008 starts in week 0.

Yes I read that but it is still misleading and -- I think -- incorrect. 
See <www.dateandtime.org/calendar> to find out that this is week 50 even 
in the UK.
We would have had a lot of misplaced business meetings in our company if 
the week numbers in Great Britain, Germany, and Sweden would actually be 
different.
