    Episode 23: Tales of Shiny in production with Pedro Silva

    Episode 23: Tales of Shiny in production with Pedro Silva

    One of the common themes seen throughout the Shiny Developer Series is that effective Shiny development is much more than just getting an application to work! Other important considerations include applying Shiny to high-profile projects, ensuring a production-grade code base, and even building robust tooling to assist with development. I have the pleasure of discussing these with Appsilon software engineer and Shiny frontend developer Pedro da Silva! You will hear Pedro's practical advice on the many developer-friendly packages and tools he uses for production Shiny development, a detailed walkthrough of his (Shiny contest) award-winning Shiny Decisions application, and his recommendations for taking your Shiny development skills to the next level.

    After a terrific showing of the eye-opening Movie Vue R in episode 26, Kent Russell and Herman Sontrop reveal the fundamental cast of R packages and workflows bringing the app to life. Kent leads us through live demonstrations of his R packages binding to Vue.js, illustrating the seamless way you can link existing HTML widgets to the Vue framework, as well as the mechanics of incorporating Shiny into existing Vue templates to unlock immense potential. Later in the episode we learn revolutionary techniques for adapting the popular crosstalk package to Vue apps, as well as a unique way of tracking application state. Each of these demonstrations reveal many nuggets of development wisdom straight from a true pioneer in bridging the amazing worlds of JavaScript and R together!

    Episode 28: The transformative effects of Shiny with the coronaSweeper app

    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!

    Episode 29: Playing fair with the FairSplit Shiny App

    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.

Ben Riedle ,

Great podcast!

Thanks for an awesome podcast that helps keep us up-to-date on new R and RStudio happenings. I am sure creating these podcasts takes a considerable amount of effort, so just wanted to say thanks for all the hard work! The podcast is a great way to learn and is much appreciated.

Jake pod dog ,

Good

I like the host and enjoy listening to this podcast.

Matt Brauer ,

Good podcast that would benefit from some editing

The host has some keen observations and insights, but could stand to cut a fair bit of material that distracts from his core content. It's really not useful to rehash one's self-doubt about an invited talk, or to emphasize multiple times how gratified one is to have been accepted as the TA for a course. I'm less interested in the personal journey, and more interested in the actual content.

(I will say though that the interview with Yihui Xie was amazing for what it was able to elicit.)
