Professional Shiny Programming
R and Shiny are an effective way to make a pilot program, which is a feasibility study on small-scale: short-term and inexpensive experiments that help an organization discover whether this project could be useful for their business. In this course we will learn how to build a pilot application that can be easily put into production to work on real data on a larger scale. We will code a Shiny application with a code organized in different Shiny Modules (“Shiny”) (clear and maintainable code) which is installed as a package (“Golem”), create unit tests (“Testthat”) to avoid regressions (TDD or TAD). A good logging system is useful to see what happens on your server: find bugs and discover user usage paths (“futile.logger”). Configuration files make the application more adaptable. Track the package environment to be reproducible (“renv”). Deploy on a Linux server using “Git” and “Github”.
