LA R Users Group - Apr 23, 2020 Meetup

LA R Users Group had our April meeting online via Zoom *Talk1* (25min talk, 5min Q&A) Speaker: Donna Wrublewski Title: Creating an R workshop experience during the ACS National Meeting Abstract: Script-based data analysis and authoring tools such as R can help researchers streamline their workflow with research data and enhance reproducibility. At the Fall 2019 Amercian Chemical Society National Meeting, two chemistry librarians partnered with a chemistry faculty member to offer a hands-on computer programming workshop. The workshop used the R programming environment, and was structured for beginners with no previous experience with R. Three main topics were covered during the five-hour session: introduction to R, working with QSAR data, and creating a report using R Markdown. This talk will cover the workshop’s logistics, instructional design, and content, and discuss feedback received from participants. Suggestions for future improvements will also be discussed. *Talk2* (25min talk, 5min Q&A) Speaker: Keren Xu Title: Draw fractals from root finding iteration in R Abstract: A talk on creating fractals by using root finding methods such as Newton Raphson and Secant method. Root-finding algorithms produce approximations to the roots (or zeroes) of a real-valued function. We will write functions with some initial guesses of the root and find better approximations of the root through iterations until the approximation reaches a sufficient precision. The functions can be applied to a complex plane and the starting values that cause the method to converge with the corresponding numbers of iterations will be mapped to draw beautiful fractals. *Talk3* (25min talk, 5min Q&A) Speaker: Luke Morris Talk title: Bracketball: Let's Explore March Madness with ncaahoopR Abstract: Whether your interest in college basketball lasts for one month or all year around, the ncaahoopR package can catch you up on the teams or games you care about, and maybe even keep you alive in that office pool a while longer. **Code of Conduct**: https://github.com/laRusers/codeofcon... *Schedule* 6:15 open zoom 6:30-7:00 First talk 7:00-7:30 Second talk 7:30-8:00 Third Talk ~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...
