What you'll learn

Understand what plots are suitable for a type of data you have
Undestand the data before you make a plot
Visualize data by creating various graphs using R base package, lattice and ggplot2 packages
A case study to select a diamond - to explain ggplot()

Requirements

Some basic knowledge of R is expected. However this course does include a quick overview of R knowledge required for this course.

Description

This course will help you draw meaningful knowledge from the data you have.

Three systems of data visualization in R are covered in this course:

A. Base Graphics B. Lattice package C. GGPlot2

A. Types of graphs covered in the course using the base R package:

Single Continuous Variable: Histogram, Density Plot, Box-Whisker Plot

Single Discrete Variable: Bar Chart

Two Continuous Variable: Scatter Plot

Two Variable: One Continuous, One Discrete: Box-Whisker Plot, Pie Chart, Dot Chart, Strip Chart

Two Variables: Both Discrete: Mosaic Plot, Stacked Bar Plot

Time series: Line Charts

B. Types of graphs covered in the Lattice package:
Histogram, Density Plot, Box-Whisker Plot, Bar Chart, Scatter Plot, Dot Chart, Strip Chart

C. Graphs covered in GGPlot2 package:
In this section you will learn about 7 layers in ggplot() and how to use these. In addition there is a project of selecting a diamond from the dataset of 54000 diamonds, based on my budget.

Commonly Used Graphs: Histogram, Density Plot, Box-Whisker Plot, Bar Chart, Scatter Plot, Dot Chart, Strip Chart
