How to Create time-series Forecast Model Web Tool via R Shiny (free)

Purpose: We are going to build a web-based tool to let user select different data sources with data exploration and present forecasting result based on ETS methodology in fpp package.

User Interface:
1. Tab 1 (Data Exploration): In this tab, users are able to select data source on the left hand side with data description. On the right hand side, it presents three main different plots, month plot, lag plot, and ACF plot.

2. Tab 2 (Forecast Methods): In this tab, it creates forecast model based on the selected data source in the Tab 1 and presents the forecast values (blue line) and range (grey shadow) based on the method on the right hand side. Also, it calculate the accuracy of model so that users can do the comparison across different methods.

Tool Structure:
R Shiny includes two main parts of codes, UI.R and Server.R. See here.
