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
