[R-SIG-Finance] [R-sig-finance] Direct Specification of Mu and Sigma in fportfolio

[reini]

Dear all, 
I was wondering whether someone can help me to solve a problem that I posted
some weeks ago: 

In using fportfolio I would like to directly specify a mu and sigma rather
than to hand over a multivariate time series from which mu and sigma are
estimated by the relevant functions. How does this work? From the
documentation it seemed possible to me, however, when I investigated the
relevant code it is asking for a time series. 

Many thanks, 
Reinhold
