I am trying to do this using the copula library and find a possible way out.
library(copula)
x=mvdc(claytonCopula(.75),c("exp","exp"),list(list(rate=1),list(rate=2)))
x.sample=rmvdc(x,100)
The above code gives a sample with two marginal exponential ditributions. But
what does the first argument claytonCopula(.75) mean? How can one specify the
correlation between these two marginals? Thanks

Subject: [R] Sampling two exponentials
Hi all,
I am going to sample two variables from two exponential distributions, but I
want to specify a covariance structure between these two variables. Is there
any way to do it in R? Or is there a "Multivariate Exponential" thing
corresponding to the multivariate normal? Thanks in advance.
