Facet dan ruang plot variabel

Alasan tidak memakai ruang plot konsisten:

Jenis variabel	Subset berisi
Kontinu	Rentang sangat berbeda
Kategorikal	Kelompok berbeda

Menyesuaikan ruang plot...

ggplot(msleep2, aes(bodywt_log,
                    brainwt_log)) +
  geom_point(alpha = 0.6, shape = 16) +
  coord_fixed() +
  facet_grid(rows = vars(vore), 
             cols = vars(conservation))

... tetapi tidak dengan skala tetap

ggplot(msleep2, aes(bodywt_log,
                         brainwt_log)) +
  geom_point(alpha = 0.6, shape = 16) +
  coord_fixed() +
  facet_grid(rows = vars(vore), 
             cols = vars(conservation),
             scales = "free_x")

Error: coord_fixed doesn't support free scales

Menyesuaikan ruang plot

ggplot(msleep2, aes(bodywt_log, 
                    brainwt_log)) +
  geom_point(alpha = 0.6, shape = 16) +
  facet_grid(rows = vars(vore), 
             cols = vars(conservation),
             scales = "free_x")

Menyesuaikan ruang plot

ggplot(msleep2, aes(bodywt_log, 
                    brainwt_log)) +
  geom_point(alpha = 0.6, shape = 16) +
  facet_grid(rows = vars(vore), 
             cols = vars(conservation),
             scales = "free_y")

Menyesuaikan ruang plot

ggplot(msleep2, aes(bodywt_log, 
                    brainwt_log)) +
  geom_point(alpha = 0.6, shape = 16) +
  facet_grid(rows = vars(vore), 
             cols = vars(conservation),
             scales = "free")

Menyesuaikan ruang plot

ggplot(msleep2, aes(x = bodywt_log, 
                    y = name)) +
  geom_point() +
  facet_grid(rows = vars(vore))

Menyesuaikan ruang plot

ggplot(msleep2, aes(x = bodywt_log, 
                    y = name)) +
  geom_point() +
  # Bebaskan skala dan ruang y
  facet_grid(rows = vars(vore), 
             scales = "free_y")

Menyesuaikan ruang plot

ggplot(msleep2, aes(x = bodywt_log, 
                    y = name)) +
  geom_point() +
  # Bebaskan skala dan ruang y
  facet_grid(rows = vars(vore),
             scales = "free_y", 
             space = "free_y")

Penyesuaian akhir

msleep2 <- msleep2 %>% 
  # Urutkan dari bobot rendah ke tinggi
  arrange(-bodywt_log) %>% 
  # Ubah level faktor sesuai urutan
  mutate(name = as_factor(name)) 

# Urutan baru tercermin di sumbu y
ggplot(msleep2, aes(x = bodywt_log,
                    y = name)) +
  geom_point() +
  # Bebaskan skala dan ruang y
  facet_grid(rows = vars(vore),
             scales = "free_y", 
             space = "free_y")
