Hadley Wickham's dplyr package is an amazing tool for restructuring, filtering, and aggregating data sets using its elegant grammar of data manipulation. By default, it works on in-memory data frames, which means you're limited to the amount of data you can fit into R's memory. Hadley also provided an extension ... [Read more...]

While many media properties including the New York Times, FiveThirtyEight and FlowingData use the R language to prepare graphics for publication, they often use Adobe Illustrator or similar graphics tools to touch up the last 5% or so of the graphics.
