Graphics in R

Graphics in R base and ggplot2 Workshop:

From Basics to Brilliance

I’m sure you’ve heard that one of R’s big advantages are its amazing graphics capabilities.

But R can be a bit…intimidating.

The downside of being able to create graphs exactly how you want them is you have to know how to get R to do exactly what you want.

In this nine hour workshop, you will learn just that.

We’ll start with drawing very basic univariate and bivariate graphs using R’s defaults and the graphics that come with Base R: scatter plots, bar charts, histograms, dot charts, pie charts and other types of graph.

Then we’ll go beyond defaults–how to customize even these basic graphs in many cool ways.

We could stop there, and you’d already have an amazing graphics toolbox.

But of course, to really capture R’s potential, you need to go beyond basics. So we’re going to explore, in detail, a very powerful package: ggplot2.

We will cover the topics at a relaxed pace, and you will have many opportunities to ask questions.

The example data sets are taken from education and the physical and biological sciences, but the ideas and syntax are applicable for creating graphs for every discipline, including business, the bio-medical sciences, psychology and the social sciences.

After taking this workshop, you will be able to create beautiful graphs for your own research or analysis.

In this Workshop, you will learn:

Part 3: Loading and using the qplot package

  • Loading the ggplot2 package

  • Mapping symbol or line size, type and color to categorical data
  • Including regressions and confidence intervals on your graph
  • Shading and coloring your graph
  • Creating bar charts, histograms, box plots, pie charts and dot charts
  • Labelling points on your graph

Part 4: Creating professional-levels graphs using qplot 

  • Creating histograms and density plots
  • Creating simple, stacked and grouped bar charts
  • Creating scatterplots and line graphs
  • Creating box plots
  • Including dates  on your graph
  • Shading and coloring your graph

Part 5: Getting started with ggplot2

  • Creating scatter graphs
  • Adding axis labels and titles
  • Controlling backgrounds, sizes, transparencies and colors
  • Mapping symbol and line size, type and color to categorical data
  • Controlling symbol shapes and using pretty color schemes
  • Modifying the axes
  • Using ggplot’s color palettes

Part 6: More customizations with ggplot2

  • Creating histograms, bar charts and box plots
  • Labelling points on your graph
  • Including regression lines and other smoothers



But can I keep up?

The workshop is pitched at a level that should make it of interest to both students and professionals.

You need some prior experience in R if you want to be able to use what you’ve learned. However, the material should be accessible to those somewhat new to R.

You do need to spend some time each week. You will learn concepts and get some clarity if you don’t practice what you’ve learned on your own. But you won’t entirely get it.

This is a workshop where you want to get your hands dirty with some data. Please expect to spend 2-3 hours per module just revising the hand-outs and doing the exercises.

This workshop is for you if you:

  • Want to learn how to create amazing graphs in R.
  • Have been using R, but would like to develop your R skills.
  • Have the time to really invest in learning. It will require about 4-6 hours per module all together.

It is not for you if you:

  • Are a complete beginner in statistics.
  • Have never seen R before.
  • Have no time to practice what you’ve learned.


  • You will get the most out of the workshop if you have had at a minimum of one statistics class.
  • You will need to have R installed on your computer.
  • You should have some experience with R. You should have at least a basic understanding of how R handles objects, data, and how to input commands and read output.

The workshop is offered as an interactive, live online workshop + Membership Site

Attend the workshop live via webinar. You will hear the instructor and see exactly what is happening on his screen. Ask questions through phone, microphone, or chat.

During the webinar sessions, the instructor will present concepts and explain the meaning of the techniques in that module, demonstrate how to implement those techniques in R on different examples, and answer your questions.

You also get video screenshot recordings of each workshop session made available within 48 hours. So you can review the material right away, a year later, or while doing the exercises. Or if you need to miss one (or all!) of the live sessions, you can still participate on your own schedule.

You will also get a membership to the workshop site. The site is our home base for the workshop. It’s where you’ll find everything you need to support your learning of each module:

Text data files. These are real data files from real research projects. You get full access to use the data to try everything on your own.

Handouts with all the R code to run and explore all of the examples yourself. You won’t learn it unless you try it. So you’ll get my code so you can follow along.

Exercises. (Yes, homework!). You really need to practice this stuff. Get your hands dirty. So we’re giving you the data to try it on your own with new models to try out. But don’t worry–you won’t be on your own stuck on some coding error that won’t work. You’ll get the code to do the exercises and the answers in case you get stuck.

But best of all, you can submit questions. So if there’s something you thought was clear during the workshop, but isn’t now that you’re reviewing the explanatory material, just type in your question. David will answer quick questions right there on the website.

Bonus videos from some webinars on relevant topics to help jog your memory or clear up misunderstandings. Included are:

– Ten Data Analysis Tips in R
– 13 Steps to Running Any Statistical Model

You’ll have access for a year to this workshop membership site. So as we add resources, re-record sessions, and answer more questions each time we offer the workshop, you have access to the updated material.
