Using R at NYT Graphics
The document discusses how R is used at The New York Times Graphics desk for various tasks like text analysis, spatial smoothing, correlations, live election forecasts, and seasonal adjustment. It provides examples of code for passing data between R and JavaScript, running R scripts asynchronously from JavaScript, and using Makefiles with R. It also notes some potential issues like packages not being installed that could cause errors when running R code.
