Create a folder called www in the original directory that contains your server.R and ui.R scripts. Place the PDF in the www/ folder, then use something like the code below:

In server.R:

shinyServer(function(input, output) {

  observeEvent(input$generate, {
    output$pdfview <- renderUI({
      tags$iframe(style="height:600px; width:100%", src="foo.pdf")
    })
  })
})

In ui.R:

shinyUI(fluidPage(

  titlePanel("Display a PDF"),

  sidebarLayout(
    sidebarPanel(
      actionButton("generate", "Generate PDF")
    ),

    mainPanel(
      uiOutput("pdfview")
    )
  )
))
