[R] manipulating weeks dates

[Ronaldo Reis-Jr.]

Hi,

I have these vectors:

> WEEK <- rep(c(1:52),2)
> YEAR <- rep(c(2000,1999),c(52,52))

How to make a vector of Date with weeks in years? I try as.date from survival 
package, but it dont work with weeks, just only with days, months etcs.

Thanks
Ronaldo
