Error saying ERROR unused argument menuItem Amazon-web-service

Question

I'm trying to create a dashboard using shiny R and I'm ending up with this error:

ERROR: unused argument (menuItem("Amazon-web-service"))

code:

shinyUI(
  dashboardPage(
    dashboardHeader(title="My First Dashboard"),
    dashboardSidebar(),
    dashboardBody(),
    menuItem("Devops"),
    menuItem("Blockchain"),
    menuItem("Amazon-web-service")
  )
)

Answer 1

This error usually means you're screwing the commas or braces somewhere in the code. In your case, menuItems function comes under dashboardSidebar function.
