I wrote a couple of ui.r and server.r codes and when I run, the package displays an aborted message saying:

R session Aborted ,R encounter a fatal error, The session was terminated.

the codes are

library(shiny)
shinyUI(fluidPage (

titlePanel(title="wow my first App"),
sidebarLayout(
sidebarPanel("this is the sidebar panel"),
mainPanel("This is the main Panel text, output displayed here")
)

)

)

and

library(shiny)
shinyServer(
function(input,output)
{

}

)

Can u please help me out? I am using R 3.1.3 at Window Vista
