Plots a surface
Usage
plot.surface(obj, lab=NA, type="p", zlab, xlab, ylab, graphics.reset = T, ...)
Arguments
obj
|
A surface object at the minimum a list with components x,y and z
in the same form as are contour and perp functions.
Also an object from a fit, for example a tps, krig, or nnreg object.

lab
|
Axes labels
|
type
|
A type="p" for a perspective plot, type="c" for a contour plot
and type="b" for both.
|
zlab
|
z-axes label
|
xlab
|
x-axes label
|
ylab
|
y-axes labels
|
graphics.reset
|
Reset to original graphics parameters after function plotting.

Description
A surface plot is generated.See Also
surface, predict.surface, as.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 list
predict.surface(fit,grid) -> out.p # evalute on a grid on two
# variables holding two fixed at their mean levels
plot.surface(out.p) # surface plot
