Below is the sample data. The task at hand is to sum quarter1 and quarter2 for ownership code 30 but exclude indcode 115. From there complete a new row that contain this sum. In excel, this is very simple but hoping to automate this a bit using R. The bottom half of the desired result is below. First question is would I pivot_wider so that I summing columns not rows?
area <- c(000000,000000,000000,000000,000000,000000,000000,000000,000000,000000,000000,000000)
indcode <- c(110,111,112,113,114,115,110,111,112,113,114,115)
quarter1 <- c(NA,2,4,6,16,3,NA,1,2,3,8,2)
quarter2 <- c(2,3,5,7,22,1,9,1,2,4,11,1)
ownership <- c(00,00,00,00,00,00,30,30,30,30,30,30)
employment <- data.frame(area,indcode,quarter1,quarter2,ownership)
area indcode quarter1 quarter2 ownership
000000 111 1 1 30
000000 112 2 2 30
000000 113 3 4 30
000000 114 8 11 30
000000 115 2 1 30
000000 993 14 18 30
I've assumed you want this done for area groups, but if not you can delete the group_by(area) line.
employment %>%
group_by(area) %>%
summarize(
across(quarter1:quarter2, ~sum(.x[ownership == 30 & indcode != 115], na.rm = TRUE)),
indcode = 993,
ownership = 30
) %>%
bind_rows(employment, .)

# 5 0 115 3 1 0
