Small Multiples and Faceting

Motivation:

• want to show more variables or dimensions at the same time

Technical Details

• we can use facet_grid or facet_wrap to do that
• you can use different types of figure like scatterplot, line, barplot
• you can use scale = “free_y” in facet function to allow different scales in different raws
• you can always use reorder() to change the order of variables
• facet_grid
  • Let the data expand according to a certain row/column in the figure
  • you can facet by two variables and specify which variable goes in rows and which goes in columns
• facet_wrap
  • jsut to display some groups and don’t need them to appear in the same row or column
