Plots a surface
Usage
surface.surface(obj, lab=NA, type="b", zlab, xlab, ylab, ...)
Arguments
obj
|
An object from a fit, for example a tps, krig, or nnreg object.
Object can also be of class surface from a predict.surface function.

lab

Axes labels
|
type
|
A type="b" for both a perspective and contour plot, type "p"
for a perspective plot and type="c" for a contour plot.
|
zlab

Description
A surface plot is generated.See Also
surface, surface.tps, predict.surfaceExamples
tps( BD[,1:4], BD$lnya)-> fit # fit surface to data
list( KCl="x", MgCl2=mean(BD[,2]),KPO4="y", dNTP=mean(BD[,4]))-> grid
# make grid
predict.surface(fit,grid) -> out.p # evalute on a grid on two
# variables holding two fixed
surface(out.p) # surface plot and contour plot
