)

Arguments

title

  • A character string will be used to set a link target. This means the user will be able to click on the application title and be redirected in a new window to whatever value is given in the string. Any valid URL, File, or other script functionality that would normally be accepted in an tag is allowed.

  • An HTML value will be used to as the HTML content for a modal pop-up window that will appear on-top of the application when the user clicks on the application title.

  • Supplying NULL will disable the title link functionality.

log_level

app_version

Character string designating the application version (default = '1.0.0')

It uses waiter (see https://waiter.john-coene.com/#/).
Pass a list like list(html = spin_1(), color = "#333e48") to
configure waiterShowOnLoad (refer to the package help for all styles).

announcements_file

[Deprecated]. Use load_announcements to configure announcement.

Value

no return value, called for setting new application global properties
