4.10 Various geoms

• geom_point(): Add points
• geom_smooth(): Fit and display smoother (e.g., regression line + standard error)
• geom_boxplot(): Produces box-and-whisker plot to summarize distribution(s)
• geom_histogram() and geom_freqpoly(): Show the distribution of continuous variables
• geom_bar(): Show distribution of categorical variables
• geom_path() and geom_line(): Draw lines between data points
  • Constrained to produce lines that travel from left to right (geom_path can go in any direction)
• These are probably not all geoms!
• Important
  • If aes() is set within ggplot(), they are inherited by other geoms that built on top.
  • If aes() is set within geom_*() it will only used within that geom.
