If a html file has become generated (as may be the default), RStudio presents a feature that permits you to place it up online rapidly.

Much more exclusively, provided a basket of stocks, there exists a notion of an efficient frontier. I.e., for just about any return you choose, there exists a portfolio with the lowest variance and for any variance you repair, there exists a portfolio with the greatest return. Any portfolio you choose that's not on this economical frontier is taken into account sub-optimum (for the presented return, why would you choose a a better variance portfolio when a decreased a single exists).
