draw: Plot the biorthogonal grid

In EnviroStat: Statistical Analysis of Environmental Space-Time Processes

Description

Function to plot the biorthogonal grid created by the bgrid function

Usage

draw(data, fs = FALSE, lwidth = c(1, 1), lcolor = c(1, 1),
     cutpts, limits = FALSE, optlist, pts = FALSE)

Arguments

data	grid object, typically as returned by the bgrid function
fs	indicator of whether non-solid lines can be used
lwidth	range of line widths to be used.
lcolor	range for colours
cutpts	cutpoints; to be created from data if not provided
limits	indicator if lower and upper limits are added to the cutpts.
optlist	list containing values of options including lwidth, lcolor, cutpts, limits; values are obtained from data if not provided.
pts	indicator whether points are also plotted.

Value

Besides drawing the grid, the function also returns optlist.

Note

See Sampson+Guttorp (1992) for detail on interpretation of the plotted grid, (E.g., solid lines indicate contraction and dashed lines indicate expansion.)
