I’m pleased to announce purrr 0.2.0. Purrr fills in the missing pieces in R’s functional programming tools, and is designed to make your pure (and now) type-stable functions purrr. I’m still working out exactly what purrr should do, and how it compares to existing functions in base R, dplyr, and tidyr. One main insight that

World Map Panel Plots with ggplot2 2.0 & ggalt
