How to change the "show entries" menu text itself?

This is a minimal example taken from user Yihui Xie :

library(shiny)
library(DT)
shinyApp(
    ui = fluidPage(fluidRow(dataTableOutput('foo'))),
    server = function(input, output) {
        output$foo = renderDataTable({
            iris
        }, options = list(
            scrollY = '300px', paging = FALSE
        ))
    }
)

How can I change the text "show x entries" to erase the word "show" , such that the menu only displays the dropdown box beside "entires" ?

If the answer involved javascript / shinyjs would you still want it ?

Yes I'm willing to try. Thanks!
