Abstract:
|
RCloud is an open source, social coding, browser/server environment for Big Data analytics and visualization developed by AT&T labs. We demonstrate RCAP, an open source RCloud package that allows Data Scientists to build R web applications similar to Shiny in the RStudio environment.
RCAP designer allows the data scientist to transform an RCloud notebook of R code into a dashboard application. This is done with a drag & drop, WYSIWYG GUI and does not require developing web code (JavaScript, CSS, etc.). A number of widgets have been developed for creating the page design, several kinds of contents (R plots, interactive plots, an iframe, etc.) and the different event controls for the page. For example, to include an R plot, one would drag and drop the RPlot widget onto the canvas. The window is sized and the user's R function is selected. Once the design elements are saved, RCAP uses RCloud to render and update the page on the fly. R functions are run in RCloud's server environment with the outputs passed to the browser via OCAP.
RCAP is a statistician's convenient web publishing tool for R analytics and visualizations developed within the RCloud environment.
