Episode 32: Consulting with Shiny Panel Discussion

Whether in a sports pickup game or a different friendly competition, we often strive for balancing the distributions of skills so everyone can have fun. What does this have to do with Shiny? In episode 29, our coverage of the 2021 Shiny contest continues as I am joined by Douglas Mesquita and Luis Gustavo Silve e Silve who created the novel FairSplit Shiny application! Motivated by regular football pickup games, Douglas and Luis developed a novel algorithm to balance the distribution of individuals incorporating multiple traits that eventually wound up into a snazzy Shiny app that easily has something for everyone. This is yet another example of the many use cases Shiny brings at your fingertips.Resources mentioned in the episodeFairSplit App - voronoys.shinyapps.io/fairsplitFairSplit Code - github.com/voronoys/fairsplitContest submission post - community.rstudio.com/t/fairsplit-shiny-contest-submission/104752Episode Timestamps00:00:00 Episode & Douglas' introduction  00:02:50 Luis' introduction  00:07:30 Fairsplit Shiny app  00:17:10 Application walkthrough  00:27:20 Sidenote: Statistical bias introduced into the system  00:47:47 Code discussion  01:12:25 Episode wrapup

The Shiny Developer Series spotlight on the 2021 Shiny Contest continues with episode 28! Eric is joined by statistics lecturer Dr. Kate Saunders to share her unique coronaSweeper Shiny application which merges a well-known mini-game in the Windows world with modelling the spread of COVID19. On the surface it might seem straight-forward, but Kate walks us through her extensive design ideas of the algorithms and user experience of the application frontend. This was a very inspiring conversation that demonstrates the ways Shiny can be transformative to teaching real principles in mathematics, statistics, and beyond!Resources mentioned in the episodecoronaSweeper App - katerobsau.shinyapps.io/Corona_SweepercoronaSweeper Code - github.com/katerobsau/coronaSweeperKate's contest submission post: community.rstudio.com/t/coronasweeper-shiny-contest-submission/104767Follow Kate on Twitter - @katerobsauEpisode Timestamps00:00:00 Episode Introduction  00:04:45 Inspiration behind coronaSweeper  00:08:15 Demo of coronaSweeper  00:14:35 Code walkthrough  00:43:10 Shiny for teaching?  00:50:20 Episode wrapup
