[R] Daily Prices, need VaR for longer periods

[Harry Holt]

I am using performance analytics and Quantmod packages.  The data is daily
stock returns, I am calculating VaR (Port.returns, p=0.95, weights =
weights, portfolio_method = "Component", method="modified").  This gives me
the Cornish Fisher VaR - daily risk.  Is there a way still using daily
prices and get longer risk periods (VaR), such as one month, or quarter?
Thanks
