Render image in UI created by r shiny

I am using R to generate an image (png file). How do I use shiny to render it to the ui?

source("#rasterBasePlot.R")
    
output$spatialMap <- renderImage ({
    filename <- PNGFileName
    
    # Return a list containing the filename
    list(src = filename)
 }, deleteFile = TRUE)

You can simply create a www folder inside your app folder and put the images you want to display there. After that something like the following should be sufficent:

library(shiny)

ui <- fluidPage(
  tags$img(
    src = "/myimage.png", width = 100
  )
)

server <- function(input, output, session) {}

shinyApp(ui, server)

If you want to use folders other than www you can use addResourcePath to add resources to Shiny's web server. Please see this.
