1. Introduction to the three major mapping systems of R
1.1 Basic drawing System (base plotting systems)
-Artist's palette: drawing suitable for blank canvas
· need to implement plans; visualize the logic of drawing and analyzing data in real time
-Two steps = figure + Modify/Add = Perform a series of functions
-Suitable for drawing 2D graphs
1.2 Lattice Drawing System (Lattice plotting systems)
-draw = Use a function call once (a graph)
-Ideal for interacting with observational variables: How variable y changes with variable x at different levels of variable Z
1.3 Ggplot2 Drawing System (Ggplot2 plotting systems)
-The Grammar of Graphics
· Figure: verbs, nouns, adjectives, etc.
· The Aesthetic attributes (color/shape/size) of data mapped to geometric objects (Points/lines/bars)
-Basic Drawing System + Lattice drawing system
· Automatically handles title/text description/space, etc., but also allows for modification by adding comments
