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 http://r.789695.n4.nabble.com/file/n3566629/Cattura.jpg -- View this message in context: http://r.789695.n4.nabble.com/problems-with-copula-tp3566629p3566629.html Sent from the R help mailing list archive at Nabble.com.
