ui.R

# -----------------------------------------------------------------------------
# This is the ui file. Use it to call elements created in your server file into
# the app, and define where they are placed, and define any user inputs.
#
# Other elements like charts, navigation bars etc. are completely up to you to
# decide what goes in. However, every element should meet accessibility
# requirements and user needs.
#
# This is the user-interface definition of a Shiny web application. You can
# run the application by clicking 'Run App' above.
