Create new column in R based upon values in two columns

Question

I have the following df, which summarizes values based on date:

df <- data_frame(
ID = c(1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20),
Date = c("28/01/2019", "28/01/2019", "29/01/2019", "29/01/2019", 
         "30/01/2019", "30/01/2019", "31/01/2019", "31/01/2019", 
         "01/02/2019", "01/02/2019", "04/02/2019", "04/02/2019", 
         "05/02/2019", "05/02/2019", "06/02/2019", "06/02/2019", 
         "07/02/2019", "07/02/2019", "08/02/2019", "08/02/2019"),
WeekYear = c("2019-05", "2019-05", "2019-05", "2019-05", "2019-05", "2019- 
              05", "2019-05", "2019-05", "2019-05", "2019-05", "2019-06", 
             "2019-06", "2019-06", "2019-06", "2019-06", "2019-06", "2019- 
              06", "2019-06", "2019-06", "2019-06"),
DayFilter = c("Public Holiday", "Public Holiday", "Work-Day", "Work-Day", 
              "Work-Day", "Work-Day", "Work-Day", "Work-Day", "Work-Day", 
              "Work-Day", "Work-Day", "Work-Day", "Work-Day", "Work-Day", 
              "Work-Day", "Work-Day", "Work-Day", "Work-Day", "Work-Day", 
              "Work-Day"),
Value = c(0, 0, 7, 3, 8, 4, 1, 0, 9, 6, 4, 5, 7, 2, 4, 9, 5, 7, 4, 1))

df

20    20 08/02/2019 2019-06  Work-Day           1

My goal is to create a new column that categorizes any week of the year that has a public holiday in it as incomplete , based upon the weekyear column. This way I can limit analyses to weeks where there were five business days

Desire output below

        ID    Date    WeekYear DayFilter      WeekFilter    Value
       <dbl> <chr>    <chr>    <chr>          <chr>         <dbl>
   1     1 28/01/2019 2019-05  Public Holiday Incomplete     0
   2     2 28/01/2019 2019-05  Public Holiday Incomplete     0
   3     3 29/01/2019 2019-05  Work-Day       Incomplete     7
   4     4 29/01/2019 2019-05  Work-Day       Incomplete     3
   5     5 30/01/2019 2019-05  Work-Day       Incomplete     8

  11    11 04/02/2019 2019-06  Work-Day       Complete       4
  12    12 04/02/2019 2019-06  Work-Day       Complete       5

  16    16 06/02/2019 2019-06  Work-Day       Complete       9
  17    17 07/02/2019 2019-06  Work-Day       Complete       5
  18    18 07/02/2019 2019-06  Work-Day       Complete       7
  19    19 08/02/2019 2019-06  Work-Day       Complete       4
  20    20 08/02/2019 2019-06  Work-Day       Complete       1

My attempts so far have successfully created a WeekFilter column with Incomplete as a value. However, it is limited to the specific date of the public holiday. The part I am struggling to figure out is how to generalize it to the rest of the week, which I figure needs to incorporate the WeekYear column into this statement

df$WeekFilter = df$WeekYear
df$WeekFilter[df$DayFilter == "Public Holiday"] <- "Incomplete"

Any assistance would be greatly appreciated

Answer 1

We may use group_by and mutate :

df %>% group_by(WeekYear) %>% 
  mutate(WeekFilter = if("Public Holiday" %in% DayFilter) "Incomplete" else "Complete")
