An interactive data analysis webapp generator for R. shiny providing a browser frontend to R backends.

1 Shiny basics

The RStudio tutorials is well done, and includes video-flavoured and text-flavoured presentations.

You can deploy public apps to the cloud via integrated service shinyapps.io.

2 Containerized webapps

Containerized apps are a convenient way to deploy code in general and to package up an interactive data analysis in particular. The dominant toolchain for this purpose seems to be Docker. R goes well in Docker. Ergo, deploying r apps to Docker seems a low lift way of doing it. Juan Camilo Orduz teaches us how to Dockerize a Shiny App, as does Paul Stevenson and there are shiny server dockerfiles. The sevenbridges dockerfiles demonstrate some sophisticated configuration.

3 Helpers

DT

The R package DT provides an R interface to the JavaScript library DataTables. R data objects (matrices or data frames) can be displayed as tables on HTML pages, and DataTables provides filtering, pagination, sorting, and many other features in the tables.
