LDAvis

cran
99.99th

Percentile

Tools to create an interactive web-based visualization of a topic model that has been fit to a corpus of text data using Latent Dirichlet Allocation (LDA). Given the estimated parameters of the topic model, it computes various summary statistics as input to an interactive visualization built with D3.js that is accessed via a browser. The goal is to help users interpret the topics in their LDA topic model.

pitchRx

cran

Percentile

With 'pitchRx', one can easily obtain Major League Baseball Advanced Media's 'Gameday' data (as well as store it in a remote database). The 'Gameday' website hosts a wealth of data in XML format, but perhaps most interesting is 'pitchfx'. Among other things, 'pitchfx' data can be used to recreate a baseball's flight path from a pitcher's hand to home plate. With pitchRx, one can easily create animations and interactive 3D 'scatterplots' of the baseball's flight path. 'pitchfx' data is also commonly used to generate a static plot of baseball locations at the moment they cross home plate. These plots, sometimes called strike-zone plots, can also refer to a plot of event probabilities over the same region. 'pitchRx' provides an easy and robust way to generate strike-zone plots using the 'ggplot2' package.
