Adding additional functions to RShiny App

I am working on a R Shiny based data analysis application. The application can take a data file and perform various data analysis, visualization functions. The idea is to add a few more analysis and visualizations functions. So, the overall idea is to extend the current version to a more advanced version.
The new features to be added would be related to data visualization (box plot, heat maps, correlation plot etc.), data aggregation, data analysis (forecast using methods like Linear Regression, Random Forest, Gradient Boosting) and improvement in the user interface.
