# difference between acf() from {stats} and Acf() from {forecast}

When I execute both functions on the same vector, I get slightly different graphs. I think I know what is happening but I want to confirm. acf() shows the spike at lag 0 which is 1 naturally, this makes the rest of the graph look much smaller. Acf() in contrast does not show the spike at lag 0 and starts at lag 1. Am I right in my assumptions?

The difference is actually explained in the forecast package manual:
