In a Shiny document, evaluate the given expression after the document has finished rendering, instead of during render.
The expression to evaluate.
An object representing the expression.
This function is useful inside Shiny documents. It delays the evaluation of its argument until the document has finished its initial render, so that the document can be viewed before the calculation is finished.
Any expression that returns HTML can be wrapped in
expr is evaluated in a copy of the environment in which
render_delayed call appears. Consequently, no side effects
expr are visible in succeeding expressions, nor are
changes to the environment after the call to
expr must be an expression that produces HTML.
