Exploring R Datasets using Shiny

• Got bored by looking at mtcars, iris and diamond datasets?
• Ever wondered what other datasets R has?
• Want to explore those datasets quickly and efficiently?
• We have got an app for you!!

Launch App

• Launching the app grabs the datasets from R installation using data(package="datasets")
• It then uses this information to populate the dropdown using selectInput()
• The data name strings are converted to variable names using get() function
• The variables in the selected data are displayed using renderUI() and selectInput() functions.
• After this, histogram is created just as in standard R:

data(CO2)
hist(CO2$uptake,
     col = "dodgerblue4")
