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

There is a simple way to do it with lubridate package:

isoweek() returns the week as it would appear in the ISO 8601 system, which uses a reoccurring leap week.

epiweek() is the US CDC version of epidemiological week. It follows same rules as isoweek() but starts on Sunday. In other parts of the world the convention is to start epidemiological weeks on Monday, which is the same as isoweek().
