This is a basic practice question in http://shiny.rstudio.com/tutorial/written-tutorial/lesson2/ and the answer also seems to match upto a certain point but when the app is run the photo is not shown even if in the working directory. Could somebody please help.

library(shiny)

# Define UI
ui <- fluidPage(
titlePanel(strong("My shiny app"), windowTitle = "My first"),

sidebarLayout(sidebarPanel(

   h1(strong("Installation")),
   p("Shiny is available on CRAN, so you can install it in the usual way from your R console:"),
   p(code('install.package("shiny")')),
   br(),
   br(),
   br(),
   br(),
   img(src = "rstudio.png", height = 70, width = 200)
                                 )
   mainPanel("main panel"))
    )

# Define server logic
server <- function(input, output) {


    }

# Run the application 
shinyApp(ui = ui, server = server)

I am still learning so the whole code has not bee written and i have no separate www/ directory as this is just for learning process. Not creating a logo or something as in the other similar question. This is just upto the image addition point.

Solution

  • You have error in code.
    Add full path to the file. Sometimes Rstudio-viewer didn't show images. But you always can open app into browser. 

    ui <- fluidPage(
  titlePanel(strong("My shiny app"), windowTitle = "My first"),

  sidebarLayout(sidebarPanel(

    h1(strong("Installation")),
    p("Shiny is available on CRAN, so you can install it in the usual way from your R console:"),
    p(code('install.package("shiny")')),
    br(),
    br(),
    br(),
    br(),
    img(src = "http://shiny.rstudio.com/tutorial/written-tutorial/lesson2/images/my-shiny-app.png", height = 70, width = 200)
  ),
  mainPanel("main panel"))
)
