Plotting a stock chart

The Quandl package is able to return data in 4 very usable formats:

data frame ("raw"),
ts ("ts"),
zoo ("zoo") and
xts ("xts")

The only thing you have to do is give the type you want as an argument to the Quandl() function.

Suppose you want to plot the end of day stock price of Facebook (Use Quandl code: WIKI/FB), with the help of the quantmod package. This package requires you to use the xts format.

Instructions
