The UseMethod call has the effect of calling
portfolio.optim.foo for the appropriate class foo.
To find the possible portfolio.optim.foo's issue
this R command:

	methods(portfolio.optim)

> tseries/help/portfolio.optim
> tseries/html/portfolio.optim.html
> tseries/latex/portfolio.optim.tex
> tseries/R-ex/portfolio.optim.R

Assuming you downloaded the source package, and not just
the binary package then the R files are all in tseries/R and 
grepping through that we find that finance.R contains it.
