Data visualization for R-R-Drawing system introduction to the three major drawing systems of 1-r

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
