"Plot,"
meaning a piece of land, came from Old English (origin around 1100), and soon
gave rise to the "graph" meaning of the term. The term
"ggplot" comes from Leland Wilkinson's book "Grammar of
Graphics," and refers to an R Project that codifies and implements
"best practices" in graphing. Dr. Randall Pruim will present
his course "Visualization in R with ggplot2," online at statistics.com.

In "Visualization in R with ggplot2", you will learn how to use the ggplot R Project to make, format, label and adjust graphs using R. The "grammar of graphics" for which ggplot is named is a system of describing and organizing the fundamental components of a graph and the process of creating a graph. Using ggplot2, participants will learn how to design and implement graphs in an efficient, elegant and systematic manner, following principles of general good graphing practice.
Who can take this course:
Statistical analysts who use R and need to
create or modify graphs.
Course Program:
Course outline: The course is structured as follows
SESSION 1: Introduction to ggplot2
- How
to create basic plots (scatterplots, histograms, and barcharts) using
qplot()
- Setting
vs. mapping
- How
to add extra variables with aesthetics (like color, shape, and size) or
faceting
SESSION 2: Finer control over plots
- The
ggplot system: geoms, stats, and all that jazz
- How
to display data in other forms (densityplots, boxplots, etc.) using geoms
- Techniques
for overcoming overplotting with drawing scatterplots of large datasets
SESSION 3: Transformations
- Group-wise
summaries and transformations to add extra information to your plots
- How
to visualize time series
SESSION 4: Polishing Your Plots
- Tweaking
your plots for maximum presentation impact
- Introduction
to color theory
- Labels,
legends, and axes
- Using
and adjusting the plot themes
Dr. Randall Pruim
is chair of Mathematics and Statistics department at Calvin College as well as
director of the Calvin’s Integrated Science Research Institute (ISRI), which
was founded in 2008 through a $1.1 million grant from the Howard Hughes Medical
Institute. Dr. Pruim is also part of Project MOSAIC, an NSF-funded initiative
to improve the teaching of modeling, statistics, calculus, and computation
nationally. The mosaic R package, available on CRAN, is a product of Project
MOSAIC that makes it easier to teach calculus and statistics using R.
This course takes place over the internet at
the Institute for 4 weeks. During each course week, you participate at times of
your own choosing - there are no set times when you must be online. The course
typically requires 15 hours per week. Course participants will be given access
to a private discussion board so that they will be able to ask questions and exchange comments with
instructor, Dr. Randall Pruim. In class discussions led by the
instructor, you can post questions, seek clarification, and interact with your
fellow students and the instructor.
For Indian participants statistics.com accepts registration for its courses
at special prices in Indian Rupees through its partner, the Center for
eLearning and Training (C-eLT), Pune.
