transforming year.weeknumber into dates
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

date from weeknumber
Hi,
Is there a function to get the last(or first) day of the week, given the
week number of the year?
For eg, week number for 7/20 is 29 as obtained by format(Sys.Date(),"%U"),
is there a function which returns 7/25 - the last day of week # 29
TIA,
Rao.

Assigning Week Numbers
R experts,
How could I extract the week number from a date vector (in Date class)
such that week numbering (week 1...2...) begins (May 01) and ends
(October 31) on the same specific dates each year? Week numbering
must conform to the following day numbering format (Sat=1,Sun=2,Mon=3.....Fri=7).
This means that new weeks must begin on Saturdays, and end on Fridays
(except for the first date
