Preface
R is a growing language that is gaining more and more space among data scientists. With over 7,000 packages, you can cover every stage within R: from data extraction, cleansing, and processing to advanced analysis, modelling, or visualization. In this context, Shiny is the tool that will take your R code to the next level, as you will be able to share all your outcomes with anyone through a dynamic web application. Shiny is not just a dashboard tool, but it is the gateway to unveiling hidden facts about data, even for nonexpert users. In other words, developing a Shiny application is like providing access to the R universe.
