textarea R variable getting an extra space-CodePudding

I use textarea (HTML) in my Shiny app.

When I put a R variable inside im geeting an extra space for example:

HTML("<textarea id='aa' dir='ltr' style='font-size: 15px; name='aa' rows='12' cols='80'>hey</textarea><br><br>") #working well

x = "hey"
HTML("<textarea id='aa' dir='ltr' style='font-size: 15px; name='aa' rows='12' 
cols='80'>",x,"</textarea><br><br>") #not working well - i'm getting " hey"

any idea?

CodePudding user response：

One option would we to wrap in paste0:

library(shiny)

x <- "hey"

ui <- fluidPage(
  HTML(
    paste0("<textarea id='aa' dir='ltr' style='font-size: 15px; name='aa' rows='12' cols='80'>", x, "</textarea><br><br>")
  )
)

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

}

shinyApp(ui, server)
