R-Studio Script development (Finance - Portfolio Opt)

I need a script in R to build and optimize a currency portfolio. The script must do the following:

1) Download history data from yahoo finance (the user will give the ticket and the start date; the end date will be the system date).

2) Create a correlation matrix between all the pairs

3) Create a vector with all the pairs with the lowest correlation (positive or negative)

4) Build a portfolio with all the currencies in that vector and obtain the weights for the min CVaR portfolio

5) Create a graph for the efficient frontier

6) Build a performance analysis of the portfolio (3 to 5 years of performance) and show the graph

7) The test must rebalance the portfolio each time it goes beyond 5%
