When there is a need for quick and comprehensive financial data in R, quantmod comes to rescue. It was originally envisioned as a rapid prototyping environment to facilitate quantitative modeling, testing, and trading. Quantmod allows R to read data from CSV files, spreadsheets, databases, datasets of statistical packages, and from the web (Google, Yahoo, FRED, and others).

> chartSeries(XPTUSD, layout=NULL, TA=NULL)
> chartSeries(XAUUSD, layout=NULL, TA=NULL)
> chartSeries(XAGUSD, layout=NULL, TA=NULL)
> layout(1)
