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)

In order to join in the themes, you'll first need to combine the sets and inventory_parts_joined tables.
Then, combine the themes table with your first join, using the suffix argument to clarify which table each name came from ("_set" or "_theme").
