R Gadget

R programming mudah di aplikasikan di gadget, di sini akan diberikan contoh sederhana aplikasi  R programming untuk gadget.

Berikut script R nya:

Script ui.R

library(shiny)
library(miniUI)
library(leaflet)
library(ggplot2)

ui <- miniPage(
  gadgetTitleBar("Example R in Gadget"),
  miniTabstripPanel(
    miniTabPanel("Parameters", icon = icon("sliders"),
      miniContentPanel(
        sliderInput("year", "Year", 1978, 2010, c(2000, 2010), sep = "")
      )
    ),
    miniTabPanel("Visualize", icon = icon("area-chart"),
      miniContentPanel(
        plotOutput("cars", height = "100%")
      )
    ),
    miniTabPanel("Map", icon = icon("map-o"),
      miniContentPanel(padding = 0,
        leafletOutput("map", height = "100%")
      ),
      miniButtonBlock(
        actionButton("resetMap", "Reset")
      )
    ),
    miniTabPanel("Data", icon = icon("table"),
      miniContentPanel(
        DT::dataTableOutput("table")
      )
    )
  )
)

Script server.R

library(shiny)
library(miniUI)
library(leaflet)
library(ggplot2)

server <- function(input, output, session) {
  output$cars <- renderPlot({
    require(ggplot2)
    ggplot(cars, aes(speed, dist)) + geom_point()
  })

  output$map <- renderLeaflet({
    force(input$resetMap)

    leaflet(quakes, height = "100%") %>% addTiles() %>%
      addMarkers(lng = ~long, lat = ~lat)
  })

  output$table <- DT::renderDataTable({
    diamonds
  })

  observeEvent(input$done, {
    stopApp(TRUE)
  })
}

Setelah di upload di server shiny.io, maka hasilnya dapat dilihat di gadget
