EnglishWhat R Packages Has Claus O. Wilke Developed?
Updated
Claus O. Wilke has authored several widely used R packages for data visualization, most notably cowplot, ggridges, and ggtext, and he is a regular contributor to ggplot2. These packages extend the grammar-of-graphics approach of ggplot2 with publication-ready themes, distribution visualizations, and formatted text. If you work in R and need finer control over multi-panel layouts, ridgeline plots, or rich text labels, these are the packages to look at.
The packages at a glance
| Package | Primary purpose | Typical use case |
|---|---|---|
| cowplot | Publication-ready theme and plot annotations for ggplot2 | Combining and labeling multiple plots into a single figure |
| ggridges | Ridgeline plots for visualizing distributions | Comparing many distributions stacked along a shared axis |
| ggtext | Formatted text in ggplot2 figures | Markdown/HTML styling in plot titles, axis labels, and annotations |
| ggplot2 | General data visualization framework | Core plotting system Wilke contributes to |
cowplot
cowplot provides a publication-ready theme and tools for annotating and arranging ggplot2 plots. It is commonly used when you need to assemble several plots into one composite figure with consistent styling and clear labels. The package is aimed at producing figures that are ready for journals or reports without extensive manual tweaking.
ggridges
ggridges creates ridgeline plots, a way to visualize distributions by stacking density curves along a shared axis. This is useful when you want to compare the distribution of a variable across many groups without the clutter of overlapping histograms or boxplots.
ggtext
ggtext enables formatted text in ggplot2 figures. It lets you add styled text — for example, using Markdown or HTML markup — to plot or axis labels and annotations. This is helpful when a plain text label is not enough and you need emphasis, color, or other formatting inside a figure.
ggplot2 contributions
Beyond authoring his own packages, Wilke is a regular contributor to ggplot2, the foundational R package for creating graphics declaratively. His work on these visualization packages builds on and extends the ggplot2 ecosystem.
Related context
Wilke is the Jane and Roland Blumberg Centennial Professor in Molecular Evolution at The University of Texas at Austin, with a PhD in Theoretical Physics from the University of Bochum. He has published extensively in computational biology, molecular evolution, protein biochemistry, and virology, and in 2019 he published Fundamentals of Data Visualization, a concise introduction to effectively visualizing many different types of data sets. His R packages grew out of this same focus on practical, effective data visualization.
