Big Data Binning
The bigvis package by Hadley Wickham is able to generate rapid binned summaries of very large vector data, however it cannot directly generate grouped binned summaries from a data.frame. The dplyr package also by Hadley is able to perform grouping on large data.frames much more quickly than his plyr package or manual subsetting. So lets combine the two packages to do grouped binning summaries of big data!
