This routine is borrowed from the cgam package. Given an object of the csvy class, which has at least two nonparametrically modelled predictors, this routine will make a 3D plot of the estimated domain mean surface with a set of two nonparametrically modelled predictors in the formula being the x and y labs.
This routine is an extension of the generic R graphics routine persp.
1 
object 
An object of the csvy class with at least two nonparametrically modelled predictors. 
x1 
A nonparametrically modelled predictor in a csvy fit. If the user omits x1 and x2, then the first two nonparametric predictors in a csvy formula will be used. 
x2 
A nonparametrically modelled predictor in a csvy fit. If the user omits x1 and x2, then the first two nonparametric predictors in a csvy formula will be used.

Arguments to be passed to the S3 method for the csvy class:

The graphic routine "plotpersp" is borrowed from the R package cgam.
See the help page of csvy
for examples.
The routine plotpersp returns a 3D plot of an object of the csvy class. The x lab and y lab represent a set of nonparametrically modelled predictors used in a csvy formula, and the z lab represents estimated domain means.
