Mastering Data Visualization with R
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
Who this course is for:
- Data Science, Six Sigma and other professionals interested in data visualization
