LA R Users - August 18 Meeting 2020 - Profiling and Benchmarking & Lesser Known Base R Features

*Talk1* (40min talk, including Q&A) Title: Dissecting a Function: Profiling and Benchmarking Your Way to Faster Code Abstract: Among the uninitiated, R is known for being slow. While this reputation is not deserved, nevertheless we sometimes write code that runs slowly for one reason or another. The process of profiling allows us to identify speed bottlenecks in our functions, while benchmarking allows us to compare the speed of alternative approaches. Let’s dig into R’s profiling and benchmarking tools and learn some tips for speeding up our code. **Speaker**: Adam Austin Adam Austin received his M.S. in Biostatistics from the University of California, Davis in 2014. Now living in the Chicago area, he works as a data scientist and manager at Allstate Insurance where he builds predictive models, coordinates the Allstate R User Group, writes R packages to improve the quality of life, and trolls the Python message boards. His spare time is largely consumed by wrangling three children, but he also enjoys bicycling, hunting, indoor rock climbing, and hipster coffee. He misses California daily. *Talk2* (25min talk, 5min Q&A) Title: Non-exhaustive list of lesser used base R features Abstract: Demonstration of several lesser known R features, including special subsetting rules, infix replacement functions, and the logic behind the base plotting paradigm. Each feature will be explored by constructing a few toy examples as well as presenting their possible use cases in the real world. **Speaker**: Karolis Koncevičius Karolis Koncevičius works as a researcher at the institute of Biotechnology in Vilnius, Lithuania, where he uses R to analyse large genomic datasets. He also teaches a course about biomedical data analysis at the Vilnius University and has authored and co-authored a few R packages: 'matrixTests', 'annmatrix', 'basetheme', 'inops', 'DiscoRhythm'. **Code of Conduct**: https://github.com/laRusers/codeofcon... *Schedule* 6:40 open zoom 6:50-7:30 Talk1 7:30-8:00 Talk2 ~8:30 Virtual Social *LA R Users Group* Invite yourself to our Slack group: https://socalrug.herokuapp.com/ Ask us any questions by email: larusers@gmail.com Find our previous talks on GitHub: https://github.com/laRusers/presentat...
