| \description{ |
| General information about the grid graphics package. |
| } |
| \details{ |
| Grid graphics provides an alternative to the standard R graphics. |
| The user is able to define arbitrary rectangular regions (called |
| \emph{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 \code{library(help = grid)} to see a list of (public) |
| Grid graphics functions. |

| ## 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, |
| w=unit(1, "inches"), h=unit(1, "inches"))) |
| ## A flash plotting example |
| grid.multipanel(vp=viewport(0.5, 0.5, 0.8, 0.8)) |
