Hello Ulrik,
Can you please explain this code means how and what this code is doing
because I'm not able to understand it, if you can explain it i can use it
in future by doing some Lil bit manipulation.
Thanks
data_help <-
data_help %>%
mutate(Purchase_ID = 1:n()) %>%
group_by(Purchase_ID) %>%
do(split_items(.))
cat_help %>% gather("Foo", "Item") %>%
filter(!is.na(Item)) %>%
left_join(data_help, by = "Item") %>%
group_by(Foo, Purchase_ID) %>%
summarise(Item = paste(Item, collapse = ", ")) %>%
spread(key = "Foo", value = "Item")
