     General information about the grid graphics package.

_D_e_t_a_i_l_s:

     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!

     Type 'library(help = grid)' to see a list of (public) Grid
     graphics functions.
