As a start you might look at the spcopula package from r-forge: install.packages("spcopula", repos = "http://r-forge.r-project.org";) Spatial copulas can also be used for interpolation in the intamap package (on CRAN). You are likely to get more responses to questions about spatial modelling o

We are interested in using copulas for spatial modeling of environmental data. We are new to R and new to copulas. We’re looking for some guidance on how to use copulas for this application. I've searched the r-help archives and I not found the information I need. Can anyone point me to informati

Hello! I am currently using R to deal empirically with copulas. I am using financial return data to construct copula models that seem appropriate for my data sets. Is there anyone who has done something similar and who is interested in talking (or writing...) with me about this topic (difficultie
