### How to fit a copula model in R heavily revised . Part 1

· It could be interesting to look at a visual take of the density of the Frank Gumbel and Clayton copula. By using the methods available in the copula package you can easily do it. Note that I have chosen arbitrary parameters for the copulas. stay tuned for part 2 of this post.
