I'm neither aware of the function `cophenet' (and RSiteSearch couldn't find it) nor the ``...Cophenet correlation coefficient...''. > that gives the agreement between the structure of the data as > interpreted by the clustering method and the original data? From this description, you're probably looking for the cophenet*ic* correlation. `cophenetic' (in package `stats' that ships with R) computes cophenetic distances, and from these and the original distances it's straighforward to get what you want using `cor'. See `?cophenetic' for examples.
