1.What does this Shiny App do
Simple Shiny App to dynamically select and display a data set This has 4 tabs that change dynamically based on input selected
- Correlation Plot to show the correlation of the features in the data set
- Summary tab to show the mean, median etc of each column in the data set
- Table tab to show the # number of observations selected from the data set
- The dynamic plot tab that displays a simple plot of x and y axis selected.
2.Example to show the summary of mtcars
