Editor's Notes
- Slide objective Establish that R is a language is as important for the community that uses it an the capabilities written to extend it than the language itself. Talking points Part 1 of the R World is The R language, developed specifically for data analysis – particularly among statisticians and mathematicians. [optional points]: Developed in New Zealand, release in roughly 2000. Maintained by the R Foundation which releases new editions of R every few weeks. Licensed under GPL open source license. R directly supports complex data manipulation operations making them extremely simple for users, particularly those with greater depth in statistics and mathematics than in computer science. Huge community of users across industry, government and academia use R daily. There are R user groups in most major cities. Some of them very active and very large. Suggest that users look at MeetUp for local groups that meet regularly. Most important to the value of R is the huge repository of freely exchanged, algorithms, techniques, scripts, adapters, techniques, training available. Introduce CRAN: “The Comprehensive R Archive Network”. Data access & integration Data transformation Data profiling Data visualization Predictive analytics Machine Learning CRAN contains over 7000 (and growing) contributed packages. Many algorithms, test data, comments on usage, etc. One package contains hundreds of algorithms packaged as a library. All are designed to run with the R language. CRAN is the largest but not the only. Thousands of additional algorithms, visualizations and tools are available from BioConductor, GitHub and other repositories. Notes
