R/Shiny Applications for Learning Statistical Concepts

Note that these applications are under regular development and expansion. Check back often.
These Shiny apps are developed by B. Dudek, Univeristy at Albany using the Shiny package from RStudio and R.
Eventually, the code for these apps will be shared within the apps.

These shiny apps may not work well with Internet Explorer or Edge at the moment. Use Firefox, Chrome, Safari.
