R: How to get the Week number of the month

Question

I am new in R.
I want the week number of the month, which the date belongs to.

By using the following code:

>CurrentDate<-Sys.Date()
>We         


        

Answer 1

You can use day from the lubridate package. I'm not sure if there's a week-of-month type function in the package, but we can do the math.

library(lubridate)
curr <- Sys.Date()
# [1] "2014-08-08"
day(curr)               ## 8th day of the current month
# [1] 8
day(curr) / 7           ## Technically, it's the 1.14th week
# [1] 1.142857
ceiling(day(curr) / 7)  ## but ceiling() will take it up to the 2nd week.
# [1] 2
