Format date as Year/Quarter

Question

I have the following dataframe:

Data <- data.frame(
  date = c(\"2001-01-01\", \"2001-02-01\", \"2001-03-01\", \"2001-04-01\", \"2001-05-01\", \"2001-06-0         


        

Answer 1

I made a similar format using quarters() and sub() in R:

Data$qtr <- paste(format(Data$date, "%y/"), 0, 
                  sub( "Q", "", quarters(Data$date) ), sep = "")
