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

I don't know any build in functions but a work around would be

CurrentDate <- Sys.Date()
# The number of the week relative to the year
weeknum <- as.integer( format(CurrentDate, format="%U") )

# Find the minimum week of the month relative to the year
mindatemonth <- as.Date( paste0(format(CurrentDate, "%Y-%m"), "-01") )
weeknummin <- as.integer( format(mindatemonth, format="%U") ) # the number of the week of the first week within the month

# Calculate the number of the week relative to the month
weeknum <- weeknum - (weeknummin - 1) # this is as an integer

# With the following you can convert the integer to the same format of 
# format(CurrentDate, format="%U")
formatC(weeknum, width = 2, flag = "0")
