library(shiny)  # define ui application plots random distributions  shinyui(pagewithsidebar(  # application title  headerpanel("hello shiny!"),    # sidebar slider input number of observations   sidebarpanel(     sliderinput("obs",              "number of observations:",              min = 1,             max = 1000,              value = 500)   ),    # show plot of generated distribution   mainpanel(     plotoutput("distplot")   ) ))

    library(shiny)      # define server logic required generate , plot random distribution shinyserver(function(input, output) {    # expression generates plot of distribution. expression   # wrapped in call renderplot indicate that:   #   #  1) "reactive" , therefore should automatically    #     re-executed when inputs change   #  2) output type plot    #   output$distplot <- renderplot({      # generate rnorm distribution , plot         dist <- rnorm(input$obs)         hist(dist)       })     })
