R Shiny img() on UI side does not render the image

问题

I have a static image in the local folder I am trying to render in the Shiny UI and it does not work. Shows a broken image with a question mark in the middle.

ui <- fluidPage(img(src = 'imagefile.png', height = '100px', width = '100px'))
server <- function(input, output) {}
shinyApp(ui = ui, server = server)

Any idea what is going on?

回答1:

Put the image in a folder called www in the same directory, so you have www/imagefile.png. Then, call

library(shiny)
ui <- fluidPage(img(src = 'imagefile.png', height = '100px', width = '100px'))
server <- function(input, output) {}
shinyAppDir(".")

But, you probably want to be using runApp with a separate ui and server file.
