shinypivottabler

The great pivottabler package enables pivot tables to be created with just a few lines of R.

The pivottabler package aims to:

All calculations for the pivot tables take place inside R, enabling the use of a wide-range of R functions in the calculation logic, and are optimized with the use of packages dplyr & data.table

shinypivottabler just adds a simple and useful Shiny module to build, visualize, customize and export custom pivot tables.

shinypivottabler vs rpivotTable ?

The rpivotTable package is visualization library built around the Javascript pivottable library.

PivotTable.js is a Javascript Pivot Table library with drag’n’drop functionality built on top of jQuery/jQueryUI and written in CoffeeScript (then compiled to JavaScript) by Nicolas Kruchten at Datacratic. It is available under an MIT license

rpivotTable is really a great pivot table library with some really cool features such as :

But it’s a full Javascript tool, and so all the data are sended to the client, and all computations are done on the client. So it’s not a good idea to use rpivotTable with a huge database.
