In the help Examples for returns(fSeries) it is said that you can pass the
method to compute ("continuous", "discrete", "compound", "simple") returns using
'type=' 
i.e.
# Discrete Returns:
   returns(MSFT, type = "discrete")
However when you use 'type' it does compute always the continuous returns, no
matter what method you select.
The only way to get the discrete returns is using 'method=' instead
i.e
# Discrete Returns:
   returns(MSFT, method = "discrete")
I think the help and pdf documentation need to be updated
