Thanks again Andy. The definition of AC is understood, yet I have trouble picturing the amount of "clear clustering structure" it measures. To put things into perspective, for two series 1,2,1000,1001 and 1,2,3,1000 agnes(x, method="single") generates ac values of 0.998998 and 0.0.7492477 respectively, yet it seems to me that both have fairly clear clustering structures.
