The example is not reproducible for us, since we do not have z. I'd try to rewrite it as follows, without having tried anything: my.cop <- normalCopula(param = 0.5, dim = 2) answer <- apply(z[,-1], 2, function(x) fitCopula(cbind(z[,1], x), my.cop, start=0.3), my.cop = my.cop) Uwe Ligges > Errors received: > Error: object "test" not found > > Could my syntax be incorrect, or is it a deeper faulty logic error. > Thank you for your help, it is much appreciated. > > aat > ______________________________________________ R-help@stat.math.ethz.ch mailing list https://stat.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide http://www.R-project.org/posting-guide.html and provide commented, minimal, self-contained, reproducible code.
