[R] Fitting Data to tCopula

[aat]

Hello,

Has anyone successfully fit empirical data to a tCopula using the fitCopula
function?  If so, are there ways to pick intelligent starting values to
avoid the errors such as a minor matrix not being positive definite and the
initial value of 'vmmin' not  being finite?

I've been able to fit a normal Copula to my data, but am having diffuculty
with the tCopula.  Any suggestions are greatly appreciated.  

Thank you.

Adam
