VolleyRotationsApp is a free and interactive Shiny web app, created and developed by Raúl Hileno, PhD, as part of the EasySportsApps GitHub project. It helps volleyball coaches visualize and plan team rotations with ease. With this app, you can create formations for two teams and see how they match up across all six rotations. Key features include:
-
Add/modify players button: Easily update court diagrams after entering player information. You can assign a number (1-99) and a name (recommended max: 10 characters, including spaces) for proper display. Team A is shown in blue, Team B in red for clear distinction.
-
Delete players button: Instantly remove all player data and reset the court diagrams to a blank state.
-
Rotation buttons: Adjust team rotations using the 'Rotate +1 position (clockwise)' and 'Rotate -1 position (counterclockwise)' buttons. To rotate multiple positions at once, use the 'Multiple rotation options' button.
-
Rotations view: Displays all six possible rotations simultaneously for both teams, allowing you to analyze player matchups. The diagrams illustrate each team's basic positions at the start of a point, before any positional adjustments or switches following the referee’s whistle.
In future versions, we are considering adding the following features:
-
Print button: Add a button in the Rotations View to easily print each team's rotations and matchups.
-
