viewer {shiny} | R Documentation

## Viewer options

### Description

Use these functions to control where the gadget is displayed in RStudio (or other R environments that emulate RStudio's viewer pane/dialog APIs). If viewer APIs are not available in the current R environment, then the gadget will be displayed in the system's default web browser (see `browseURL`).

### Usage

    paneViewer(minHeight = NULL)

    dialogViewer(dialogName, width = 600, height = 600)

    browserViewer(browser = getOption("browser"))

### Arguments

`minHeight` | The minimum height (in pixels) desired to show the gadget in the viewer pane. If a positive number, resize the pane if necessary to show at least that many pixels. If `NULL`, use the existing viewer pane size. If `"maximize"`, use the maximum available vertical space.
`dialogName` | The window title to display for the dialog.
`width, height` | The desired dialog width/height, in pixels.
`browser` | See `browseURL`.

### Value

A function that takes a single `url` parameter, suitable for passing as the `viewer` argument of `runGadget`.
