Have you looked at the findTemplate() function? It performs a sliding window correlation. You may need to monkey with the threshold to get it right. You can pick between a variety of correlation methods. If you need the raw correlation data you might need to write your own function following the findTemplate method as a template. If you do this send me a pull request and I can add it to the library.
