Exercise

Combining sets

The data you aggregated in the last exercise has been preloaded for you as batman_colors and star_wars_colors. Prior to visualizing the data, you'll want to combine these tables to be able to directly compare the themes' colors. 

batman_colors <- inventory_parts_themes %>%
  filter(name_theme == "Batman") %>%
  group_by(color_id) %>%
  summarize(total = sum(quantity)) %>%
  mutate(fraction = total / sum(total))

star_wars_colors <- inventory_parts_themes %>%
  filter(name_theme == "Star Wars") %>%
  group_by(color_id) %>%
  summarize(total = sum(quantity)) %>%
  mutate(fraction = total / sum(total))
