想要根据三维的fgmcopula生成随机变量值，但是运行过程报错，代码为
mv.NE <- mvdc(fgmCopula(c(0.06, 0, 0, 0), dim=3), c("pareto","pareto", "pareto"), list(list(scale = 0.5, shape =0.4), list(scale = 0.3, shape =0.4), list(scale = 0.6, shape =0.4)))
y.samp <- rMvdc(40, mv.NE)

报错信息为：
Warning message:
In .local(n, copula, ...) :
  random generation in C needs to be properly tested

有没有大佬知道？
