viewer function

Viewer options

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 utils::browseURL()).

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 utils::browseURL().

Returns

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