Visualize mixed effect regressions in R with GGplot2
In this post, I will show some methods of displaying mixed effect regression models and associated uncertainty using non-parametric bootstrapping. This is kind of a follow-up to my previous post […]
Biomass Pyramids and Funnel Plots in R with GGplot2
Every once in a while, I come across a plot form that is not in my ggplot repertoire. For example, I occasionally want to make a funnel plot in my […]
Plotting custom models with ggplot2 in R
Last week, I attended a talk at our local Yale data science group by my friend Matteo in which he presented an overview of ggplot2. During the questions after the […]
Web scraping and text analysis in R and GGplot2
I recently needed to learn text mining for a project at work. I generally learn more quickly with a real-world project. So, I turned to a topic I love: Wilderness, […]
Species range maps with GGplot
The other day, I wanted to tweet out a map showing the distribution of some wood frog tissue samples compared to the entire range of the species. I’m not much […]
