Why I use ggplot2

If you’ve read my blog, taken one of my classes, or sat next to me on an airplane, you probably know I’m a big fan of Hadley Wickham’s ggplot2 package, especially compared to base R plotting.

Here’s a short example of how to read that WKT and plot the logo using ggplot2: library(sp) library(maptools)

ggseas package for seasonal adjustment on the fly with ggplot2

In a post a few months ago I built a new ggplot2 statistical transformation (“stat”) to provide X13-SEATS-ARIMA seasonal adjustment on the fly. With certain exploratory workflows this can be useful, saving on a step of seasonally adjusting many different slices and dices of a multi-dimensional time series during data reshaping, and just drawing it for you...

Repel overlapping text labels in ggplot2

A while back I showed you how to make volcano plots in base R for visualizing gene expression results. This is just one of many genome-scale plots where you might want to show all individual results but highlight or call out important results by labeling them, for example, with a gene name. But if you want to annotate...
