Differences between Batman and Star Wars
In the video, you compared two sets. Now, you'll compare two themes, each of which is made up of many sets.
First, you'll need to join in the themes. Recall that doing so requires going through the sets first. You'll use the inventory_parts_joined table from the video, which is already available to you in the console.
inventory_parts_joined <- inventories %>%
inner_join(inventory_parts, by = c("id" = "inventory_id")) %>%
arrange(desc(quantity)) %>%
select(-id, -version)
