Pittsburgh useR Spring Meeting

Agenda for this meeting:

• Sam Ventura, "Scraping, Reading, and Creating JSON Data with R"

JavaScript Object Notation (JSON) data is an increasingly popular way to display tabular data on websites, since it's easy for humans to read and easy for computers to parse and generate. However, websites that use JSON data cannot be scraped using traditional approaches (e.g. using regular expressions on HTML code or R's XML package). I overview some incredibly simple packages, functions, and approaches for loading JSON data from the web into R. I demonstrate how to convert your own R data.frames into JSON objects for those who are interested in sharing data and results publicly. Finally, I show some applications of JSON-to-R conversions by doing (gasp!) live demonstrations.

• Bronwyn Woods, "rCharts package for using javascript plotting tools through R/shiny"

• Mikhail Popov will announce the details of the first ever Pittburgh useR data analysis competition!
