The server function of the modal module — modalServer • shinyngs

This module uses Shiny's modalDialog() to create overlaid text for the current panel which displays when the link produced by modalInput() is clicked. It is called from the server function of the calling module, using the same id passed to modalInput (see example).

Usage

modalServer(id, title, content = NULL)

Arguments

id: Modal ID. Must match that passed to modalInput
title: Title to show on the help modal. May be a function, which is called each time the modal opens, so titles that depend on reactive state stay current.
content: Content to include in the modal. May be a function, called each time the modal opens. When NULL (the default), Markdown is loaded from inst/inlinehelp/<id>.md the first time the modal is opened, then cached for the life of the session.

Details

This is handy, for example when adding help text.

Examples

modalServer("dendro", "Sample clustering dendrogram")
#> Error in modalServer("dendro", "Sample clustering dendrogram"): could not find function "modalServer"
