General information about the grid graphics package.
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!

## Diagram of a simple layout
grid.show.layout(grid.layout(4,2,
heights=unit(rep(1, 4),
c("lines", "lines", "lines", "null")),
widths=unit(c(1, 1), "inches")))
## Diagram of a sample viewport
grid.show.viewport(viewport(x=0.6, y=0.6,
width=unit(1, "inches"), height=unit(1, "inches")))
## A flash plotting example
grid.multipanel(vp=viewport(0.5, 0.5, 0.8, 0.8))
