plot(x, what, type, which, col.args, col.contour,
	    level.at, border, theta, phi, shade, ...)

`x`	sssFit object from scp.
`what`	character. What to plot? One of obs (for observed responses), fit (for fitted values, the default) or g (for the estimated bivariate spline).
`type`	character. Which type of plot? One of image (the default), levelplot, persp or persp3d.
`which`	character. Which color pattern? One of colorRampPalette (default), colorRamp, rainbow, heat.colors, terrain.colors, topo.colors, or cm.colors.
`col.args`	named list. List with argument to pass to the color pattern function defined by `which`. See colorRampPalette, colorRamp, rainbow, heat.colors, terrain.colors, topo.colors, and cm.colors.
`col.contour`	character. Only for `type="image"`. Color for the contours.
`level.at`	character or numeric vector. Only for `type="levelplot"`. Where to draw the levels at. If character, it is the name of the function to compute where to put the levels.
`border`	character. Color of the border.
`theta, phi, shade`	numeric. See persp or persp3d.
`...`	other arguments for levelplot, image, persp or persp3d.
