This is a R-Shiny App for computing and plotting the Markowitz mean-variance efficient frontier. Most of the hard work is done by the fPortfolio package which is part of Rmetrics.

The App consists of three R files:

• As in all Shiny Apps, ui.R is the user interface script handles the user experience: it sets the page details (the way the app looks like), lists the input options and defines the output formats.

• The server script (server.R) does all the R work, meaning it handles all the input calls and instructions given to the app and returns the output to be displayed on the page.

• The file my-fpoints.R is optional (it is used only if use_original_frontierPlot is set to FALSE at the top of server.R). It defines a more robust version of frontierPlot which handles degenerate efficient frontiers without errors.
