Mengatur elemen tema

ggplot(iris, aes(x = Sepal.Length, y = Sepal.Width, color = Species)) + 
  geom_jitter(alpha = 0.6) +
  theme(axis.title = element_text(color = "blue"))

Plot awal...

ggplot(iris, aes(x = Sepal.Length, y = Sepal.Width, color = Species)) + 
  geom_jitter(alpha = 0.6)

Elemen garis

theme(
line,
  axis.ticks,
    axis.ticks.x, 
      axis.ticks.x.top,
      axis.ticks.x.bottom,
    axis.ticks.y,
      axis.ticks.y.left,

      panel.grid.major.y, 
    panel.grid.minor,
      panel.grid.minor.x,
      panel.grid.minor.y)

Plot awal...

ggplot(iris, aes(x = Sepal.Length, y = Sepal.Width, color = Species)) + 
  geom_jitter(alpha = 0.6)

Elemen persegi

theme(
rect,
  legend.background, 
  legend.key,
  legend.box.background, 
  panel.background,
  panel.border,
  plot.background, 
  strip.background, 
    strip.background.x, 
    strip.background.y)

Penamaan hierarkis mencerminkan aturan pewarisan

      axis.title.x.top
      axis.title.x.bottom 
    axis.title.y
      axis.title.y.left
      axis.title.y.right

mis. Garis

element_blank()

ggplot(iris, aes(x = Sepal.Length, y = Sepal.Width, color = Species)) + 
  geom_jitter(alpha = 0.6) + 
  theme(line = element_blank(),
        rect = element_blank(),
        text = element_blank())
