[R-sig-finance] portfolio.optim, where is the source code

[Omar Lakkis]

How do I see the code (actual implemetation) of the function
portfolio.optim() in tseries?

When I type the function's name on teh command line I get:
> portfolio.optim  
function (x, ...) 
UseMethod("portfolio.optim")

I was unable to find the source in my installation. 

/usr/local/lib/R/site-library$ find tseries/ | grep op
tseries/help/portfolio.optim
tseries/html/portfolio.optim.html
tseries/latex/portfolio.optim.tex
tseries/R-ex/portfolio.optim.R
