Request a re-rendering of the Panel output via reactive variables.
.requestUpdate(panel_name, rObjects)
.requestCleanUpdate(panel_name, pObjects, rObjects)
.requestActiveSelectionUpdate(
panel_name,
session,
pObjects,
rObjects,
update_output = TRUE
)String containing the panel name.
A reactive list of values generated in the iSEE app.
An environment containing global parameters generated in the iSEE app.
The Shiny session object from the server function.
A logical scalar indicating whether to call .requestUpdate as well.
.requestUpdate will modify rObjects to request a re-rendering of the specified panel.
.requestCleanUpdate will also remove all active/saved selections in the chosen panel.
.requestActiveSelectionUpdate will modify rObjects to indicate that the active multiple selection for panel_name has changed.
If update_output=TRUE, it will also request a re-rendering of the panel.
All functions will invisibly return NULL.
.requestUpdate should be used in various observers to request a re-rendering of the panel,
usually in response to user-driven parameter changes in .createObservers.
.requestCleanUpdate is used for changes to protected parameters that invalidate existing multiple selections,
e.g., if the coordinates change in a DotPlot, existing brushes and lassos are usually not applicable.
.requestActiveSelectionUpdate should be used in the observer expression that implements the panel's multiple selection mechanism.
.createProtectedParameterObservers, for examples where the update-requesting functions are used.
