[R] problems with copula

[ANGELA86]

Hi, I'd like to know why using the program "R" I can't add a number of
margins> 3,  I have a problem with the graphics. 
Post here my script:
> myCop.norm <- ellipCopula(family = "normal", dim = 3, param = 0.4)
> myMvd <- mvdc(copula = myCop.norm, margins = c("norm", "norm","norm"),
> paramMargins = list(list(mean = 0, sd = 2), list(mean = 0, sd =
> 1),list(mean=0,sd=2)))
persp(myMvd, dmvdc, xlim = c(-4, 4), ylim=c(-4, 4),main="Normal copula")

I  obtain the following  message of error :
"Error in eval  index out of bound" 


Help me!!!! thanks
