By default, the margin is filled with light grey, the new viewport is filled with white and framed with a black border, and the viewport region is filled with light blue and framed with a blue border. The diagram is annotated with the width and height (including units) of the viewport, the (x, y) location of the viewport, and the x- and y-scales of the viewport, using red lines and text. </p> <h3>Value</h3> <p>None. </p> <h3>Author(s)</h3> <p>Paul Murrell</p> <h3>See Also</h3> <p><a href="Grid.html">Grid</a>, <code><a href="viewport.html">viewport</a></code> </p> <h3>Examples</h3> <pre> ## Diagram of a sample viewport grid.show.viewport(viewport(x=0.6, y=0.6, w=unit(1, "inches"), h=unit(1, "inches"))) grid.show.viewport(viewport(layout.pos.row=2, layout.pos.col=2:3), grid.layout(3, 4)) </pre> <hr /><div style="text-align: center;">[Package <em>grid</em> version 3.6.0 <a href="00Index.html">Index</a>]</div> </body></html>
