Hi Dan,
For this to work, the copula package should
explicitly import dmvnorm from the mvtnorm
package by including
importFrom(mvtnorm, dmvnorm)
in their NAMESPACE file.
You can do the same thing and rebuild + reinstall
the package to solve your problem quickly, but
there might be some other imports of relevance
(I cc'ed the maintainer).
Best,
Tobias

I am using curve3d in the emdbook package to graph a gaussian copula density
function generated via the copula package. Unfortunately, it appears that
emdbook masks dmvnorm from the package mvtnorm in a way that prohibits
copula from generating the gaussian copula. (Sounds very confusing!) For
example,
library(copula)
f<-function(x,y) dcopula(normalCopula(0),c(x,y))
library(emdbook)
curve3d(f)
Error in dmvnorm(x, sigma = sigma) : unused argument(s) (sigma = sigma)
Is there no way for me to use those two libraries together?
Thanks,
Dan
