Dennis, David, The code I'm running is from here:

http://www.r-bloggers.com/nonparametric-copula-density-estimation/

s comes from  here:



s {mgcv}

*Defining smooths in GAM formulae*

*Package: *

 mgcv

*Version: *

 1.7-24

*Description*

Function used in definition of smooth terms within
*gam*<http://inside-r.org/r-doc/mgcv/gam> model
formulae. The function does not evaluate a (spline) smooth - it exists
purely to help set up a model using spline based smooths.

*Usage*

s(..., k=-1,fx=FALSE,bs="tp",m=NA,by=NA,xt=NULL,id=NULL,sp=NULL)

The mgcv package is installed and loaded






la function persp  is in  the package  graphics   persp {graphics}

*perspective plots*

*package: *

graphics

*version: *

r 3.0.1
try installing graphics and tells me it can not be installed in version
3.0.1 of R
