I want to calculate a weeks start date given week number and year.
For that, I tried to use as.Date function and formatting stated below. But the same function is not working or it is returning NA when week number is 53.
+ format = "%Y-%U-%u")  "2020-12-28" > as.Date(x = "2020-53-1", + format = "%Y-%U-%u")  NA```. It seems it is not working for week number 53/ or it is giving output a week ahead.
