Package: shinyEvents 2.3

shinyEvents: Shiny wrapper with event handlers instead of reactivity

Shiny is a great package. Yet, for more complex projects, with much dynamic UI, I find it hard to write clean code with its reactivity paradigm. This package wraps shiny into a more traditional programming approach: - event handlers for input changes and button clicks - explicit update functions to change outputs - no explicit server function
