Hello!
I know how to transform dates into year.weeknumber format using zoo:
library(zoo)
as.numeric(format(as.Date("2010-10-02"), "%Y.%W"))
But is there a straightforward way to do the opposite - to transform
character strings like "2009.12" or "2009.30" back into dates
(assuming that weeks start on Monday)?
Thanks a lot!
