The expected output should be a data frame with the PAN ID, the week, the brand ID, and the difference in weeks between each consecutive week. Here’s how you could achieve this: First, let’s create a new column that calculates the number of weeks since the first purchase for each PAN ID and brand ID: library(dplyr) df %>% group_by(PANID, brandID) %>% mutate(first_purchase = ifelse(is.na(WEEK), as.Date("2001-01-01"), WEEK)) %>% ungroup() %>% arrange(PANID, brandID) This will create a new column called first_purchase that contains the first date of purchase for each PAN ID and brand ID.
