ui.R -> a minimal example

shinyUI(fluidPage( # flexible layout function


titlePanel("Den minimala applikationen"),

textInput(inputId = "comment", # this is the name of the
# variable- this will be passed to server.R
label = "Säg något", # display label for the variable
value = "" # initial value


# Show a plot of the generated distribution
mainPanel( # main output configuration
  h3("This is you saying it"), # title with HTML helper
  textOutput("textDisplay")    # this is the name of the output
  # element as defined in server.R
