-
Explains the structure of ggplot2, grammar of graphics, and geometric objects
-
Covers designing and implementing a visualization from scratch
-
Explores the advantages of using advanced plots
This course introduces you to the world of data visualization by talking about the basic features of ggplot2. Learn all about setting up the R environment and then begin exploring the features of ggplot2. Grammar of graphics and geometric objects are the fundamentals you must know before you dive deep into the plotting techniques. Read and discover what are layers, scales, coordinates, and themes, and explore how you can use them to transform your data into aesthetical graphs. Learn the simple plots, such as histograms, and then some advanced plots, such as superimposing plots and density plots. Learn to plot trends, correlations, and statistical summaries. After reading this course, your data visualizations will wow clients.
This course is meant for professionals, who work with data and R, and for students, who want to enhance their data analysis skills by adding informative and professional visualizations. We assume that readers know the basics of the R language, its commands, and objects.
