How to take data that is in "long format" into "wide" format but keep some categorical columns the same

I have this data set that's in "long format" which I have listed below.

enter image description here

My goal is convert this data into a shorter format. I have this code but I keep getting NA's in the Sum column.

data %>% 
group_by(Month, Year, Status) %>% 
  summarise(Sum = sum(Count))

enter image description here

data

data <- structure(list(Month = c("Oct", "Oct", "Oct", "Oct", "Oct", "Oct", 
"Oct", "Oct", "Oct", "Oct", "Oct", "Oct", "Oct", "Oct", "Oct", 
"Oct", "Oct", "Oct", "Oct", "Oct", "Oct", "Oct", "Oct", "Oct", 
"Oct", "Oct", "Oct", "Oct", "Oct", "Oct", "Oct", "Oct", "Oct", 
"Oct", "Oct", "Oct", "Sep", "Sep", "Sep", "Sep", "Sep", "Sep", 
"Sep", "Sep", "Sep", "Sep", "Sep", "Sep", "Sep", "Sep", "Sep", 
"Sep", "Sep", "Sep", "Sep", "Sep", "Sep", "Sep", "Sep", "Sep", 
"Sep", "Sep", "Sep", "Sep", "Sep", "Sep", "Sep", "Sep", "Sep", 
"Sep", "Sep", "Sep"), Year = c(2021L, 2021L, 2021L, 2021L, 2021L,

You pretty much have the code correct. You just need to account for the NAs with na.rm = TRUE.

library(dplyr)

data %>%
  dplyr::group_by(Month, Year, Status) %>%
  dplyr::summarise(Sum = sum(Count, na.rm = TRUE))

Output

# A tibble: 4 × 5
# Groups:   Month, Year [2]
  Month  Year Status     Sum
  <chr> <int> <chr>    <int>
1 Oct    2021 Active     977
2 Oct    2021 Inactive   843
3 Sep    2021 Active     797
4 Sep    2021 Inactive   675

Then, if you want to get the percentage for each Status by Month and Year, then you can mutate a new column.

data %>%
  dplyr::group_by(Month, Year, Status) %>%
  dplyr::summarise(Sum = sum(Count, na.rm = TRUE)) %>%
  # Need to ungroup the Status column.
  dplyr::ungroup(Status) %>%
  dplyr::mutate(percent = (Sum / sum(Sum)) * 100)

Output

# A tibble: 4 × 5
# Groups:   Month, Year [2]
  Month  Year Status     Sum  percent
  <chr> <int> <chr>    <int> <dbl>
1 Oct    2021 Active     977  53.7
2 Oct    2021 Inactive   843  46.3
3 Sep    2021 Active     797  54.1
4 Sep    2021 Inactive   675  45.9

I think you just needed the na.rm = TRUE part in the Sum

out <- data %>%
  dplyr::group_by(Month, Year, Status) %>%
  dplyr::summarise(Sum = sum(Count, na.rm = TRUE))

out
# A tibble: 4 x 4
# Groups:   Month, Year [2]
  Month  Year Status     Sum
  <chr> <int> <chr>    <int>
1 Oct    2021 Active     977
2 Oct    2021 Inactive   843
3 Sep    2021 Active     797
4 Sep    2021 Inactive   675
