Create a Perspective Proxy Object for Shiny

Usage

perspectiveProxy(session, outputId)

Arguments

session

The Shiny session object (usually session).

outputId

The output ID of the Perspective widget to control.

Value

A proxy object of class "perspective_proxy".

Examples

if (interactive()) {
server <- function(input, output, session) {
  output$viewer <- renderPerspective({
    perspective(mtcars)
  })

  observeEvent(input$add_data, {
    proxy <- perspectiveProxy(session, "viewer")
    psp_update(proxy, new_data)
  })
}
}
