Source: R/shiny.R

Usage

glmap_proxy(outputId, session = NULL, data = NULL, deferUntilFlush = TRUE)

Arguments

outputId

The ID of the glmapOutput control in the Shiny UI.

session

The Shiny session object (defaults to shiny::getDefaultReactiveDomain()).

data

Optional default data object associated with proxy calls.

deferUntilFlush

Logical; whether to buffer commands until after the next reactive flush.

Value

A glmap_proxy object that can be piped into add_*(), clear_layer(), fly_to(), etc.
