The awesome folks at Quandl
(an amazing data collection and distribution service) have been so kind as to allow me to write for their blog.
In my first post for them I demonstrate (with detailed R code) how a user of their free data services could easily compare the relationship between time series data in different markets. In my particular post I compare the bitcoin (sometimes mistakenly referred interchangeably with bitstamp) market with that of the gold market.
Find the post, "Investigating the relationship between gold and bitcoin prices useing R" here.
