DSCI 325: Handout 26 – Introduction to R Shiny Spring 2017 Shiny is an R package that allows users to build interactive web applications using R. Programming in Shiny is more involved than using the manipulate function, but it also offers more flexibility and is worth the extra effort. RStudio has put together an excellent tutorial on Jul 16, 2019 · If you developed a shiny app before, you had to think about the user interface (UI) and the server side. The code to create the UI probably landed in the file ui.R, the server function in a server.R file (or you combined both of them in app.R). As soon as the app gets a bit more complex, the two files get bigger and quickly confusing. shiny-package Web Application Framework for R Description Shiny makes it incredibly easy to build interactive web applications with R. Automatic "reactive" binding between inputs and outputs and extensive pre-built widgets make it possible to build beau-tiful, responsive, and powerful applications with minimal effort. Both, renderPlot and renderPrint compute the linear regression model. While the first needs only the output, the second needs some values that are stored in the lme variable (here the intercepts).
