Setting a header
In the videos, the header was likened to the signboard or front-end of a restaurant.
In the header, the title of the shinydashboard is defined, and additional elements can be added. Particularly, you saw various types of dropdown lists containing various types of items.
In this exercise, imagine that you have already carried out an analysis of some statistics for a global soccer tournament. You now want to create a dashboard as a means to present these results. To this end, you will first set up the header.
The shiny
and shinydashboard
packaged have already been loaded for you.
This exercise is part of the course
