##### Details

Grid graphics provides an alternative to the standard R graphics. The user is able to define arbitrary rectangular regions (called viewports) on the graphics device and define a number of coordinate systems for each region. Drawing can be specified to occur in any viewport using any of the available coordinate systems.

Grid graphics and standard R graphics do not mix!
