how to add multiple line breaks conveniently in shiny?

Question

I want put multiple line breaks in my shiny app. Instead of

br(),
br(),
br(),
...

is there any more convenient way of doing it?Thanks.

The easiest way would be to modify your css https://stackoverflow.com/questions/2703601/how-to-give-line-break-from-css-without-using-br — amrrs, Oct 04 '17 at 07:53

Seems pretty convenient to me - only 5 characters and stays in the Shiny idiom (no javascript). What kind of convenience are you looking for? — Mike Wise, Nov 20 '17 at 08:47
@MikeWise Like 10 lines of breaks......putting 10 lines of `br(),` doesn't really cost too much, but that's not what programming does...is it? Programming is supposed to do these repetitive things as I understand... — rankthefirst, Nov 21 '17 at 09:50

I have no idea if that's convenient for you, but it saves you some typing.

linebreaks(n) repeats <br/> n times and parses it as HTML.

library(shiny)


linebreaks <- function(n){HTML(strrep(br(), n))}

ui <- fluidPage(

  titlePanel(
              p( 
                  h1("first sentence", align = "center"),

                  linebreaks(10),

                  h3("second sentence", align = "center")
                )
              )
  )

I'm defining the function. ```linebreaks <- function(n){HTML(strrep(br(), n))}``` – Humpelstielzchen May 27 '21 at 19:12
