You can do like this:

library(shiny)
ui <- fluidPage(titlePanel("Getting Iframe"), 
                sidebarLayout(
                  sidebarPanel(
                    textInput("url", label = "Enter url"), 
                    actionButton("go", "Go")
                  ),
                  mainPanel(
                    htmlOutput("frame")
                  )
                ))

server <- function(input, output) {
  output$frame <- renderUI({
    validate(need(input$go, message=FALSE))
    tags$iframe(src=isolate(input$url), height=600, width=535)
  })
}

shinyApp(ui, server)

I get a white iframe. I thought it was slow so i waited but nothing comes up. I get an error if i type "www.google.com". Instead get a white space with "https://www.google.com" – Claudio Paladini Aug 27 '17 at 06:12
Other websites work but Google doesn't seem to allow this. – Claudio Paladini Sep 24 '20 at 13:41
