Abstract:

The grid package (P. Murrell, 2005) is a good tool for visualizing forestry data. The viewport, a main feature of grid, makes it possible to visually compare groups of plots arranged spatially. For instance, several viewports can be used to construct multiple caveplots (Becker et al,1994) for visualizing lightning and fire ignition data at different locations. They can also be used to modify pairwise scatterplots for exploring relationships among fire weather variables and danger ratings. The editing of grid objects (grobs) makes animating graphics in R easier. As an example, we introduce the Fengche plot for visualizing wind data. In this talk we argue that grid is easy enough to use that it should replace some traditional plotting tools.
