Create an interval plot for spatial grid.
Calls spplot to plot the locations, centers, and radii of an intgrd object in a single figure.
## S4 method for signature 'intgrd,missing' plot(x, beside = TRUE, circleCol = "black", minRad = 0.25, ...)
x: An object of class intgrd.beside: Tf true, center and radius plotted side by side if false, center and radius are plotted in a single figure with the center plotted using color and the radius plotted using circles circumscribed within each grid cell.circleCol: If beside=TRUE, the color of the circles that will be circumscribed within each grid cell.minRad: The minimum value of the radius in the circles drawn to represent the interval radii. Must be a number between 0 and 1 where approaching 0 results in a point being drawn in the center of the grid, while approaching 1 results in every circle being circumscribed in their respective grid cell (which is not very interesting)....: Additional arguments to spplot.Useful links
