Data Visualisation in R: Harnessing the power of ggplot2 to produce elegant
data graphics
Mango Solutions is delighted to offer a one-off 2 day training course with Dr.
Hadley Wickham, R Project Data Visualisation Guru and creator of ggplot 2. The
course is a must for any R user looking to improve their data visualisation
skills. Suitable for any level of R experience, it will especially benefit
those who know how to get data in and out of R and who can do some basic
modelling.
Places will be limited on what will be a very popular course.
Course Content:
Day One
Basic graphics
- How to create scatterplots, and how to add extra variables with aesthetics
(like colour, shape and size) or facetting. Jittering, histograms and
reordering. Coding strategy best practices.
- Data: fuel economy of US cars.
Graphics for large data
- Histograms and bar charts for displaying distributional summaries. More
boxplots. Other techniques for overcoming overplotting when drawing
scatterplots of large datasets.
- Data: prices and characteristics of 50,000 diamonds.
Data manipulation and transformation
- Group-wise summaries and transformations to add extra information to your
plots. How to visualise time series.
- Data: trends in US baby names over the last 120 years.
Data analysis case study
- Iteration between graphics, transformation and modelling. More practice using
ddply, and combining it with other R functions.
- Data: US baby names
Day Two
Visualising space
- What is map data and how can you draw it? Working with shape files. Basic
ggplot2 theory. How to combine multiple layers. Combining maps with data.
Choropleths/themeatic maps, proportional symbol maps.
- Data: Texas mortality and worldwide TB infections
ggplot2 theory and graphical critique
- How to critique a graphic (how is a graphic like pumpkin pie?) What is the
layered grammar of graphics and why is it important? Using the grammar to
create richer plots.
Polishing your plots for presentation
- Tweaking your plots for maximum presentation impact. Introduction to colour
theory. Labels, legends and axes. Tweaking the plot themes.
Where to next
- General development advice.
Hadley Wickham is the Dobelman Family Junior Chair in Statistics at Rice
University. He is an active member of the R community, has written and
contributed to over 20 R packages and won the John Chambers Award for
Statistical Computing for his work developing tools for data reshaping and
visualisation. His research focuses on how to make data analysis better, faster
and easier with a particular emphasis on the use of visualisation to better
understand data and models.
