# How do you interpret a changepoint graph?

What is the correct way of interpreting a changepoint graph? Here is what R gives for changepoint analysis of the mean of a data set:

----------
Changepoint type      : Change in mean
Method of analysis    : AMOC
Assumed Distribution  : Normal
Type of penalty       : SIC with value, 4.770685
Maximum no. of cpts   : 1
Changepoint Locations : 15 118


So changes occurred at t=15 and t = 118?

out<-cpt.mean(data)
