This repository contains the files of the 'Guess-The-Torus' web application.
The application has been created for the Developing Data Products course using the Shiny R package. Following is a brief description of the files in this repository:

• README.md - this file
• ui.R - web application user interface (required by Shiny)
• server.R - server-side event handling R script (required by Shiny)
• MakeSimpleTorusData.R - contains the function used to generate 2 data sets - training.set and test.set
• Make3DTorusSurfPlot.R - contains the function used to plot a 3D surface using the plot3D R package
• Make3DScatterPlot.R - contains the function used to generate a 3D scatterplot of a sample from the training data set using the scatterplot3d R package

The application allows a user to specify the size of the data sets (both training and testing) and then to input 3D points (as a tuple of Cartesian coordinates x, y and z) and use the K-Nearest Neighbors model trained on the training set to predict whether the 3D point is inside a torus or not.

The web page contains a brief description of the application. For additional details, see the slidify description of the application.
