AnomalyDetectionVec Vector needs to be periodic?

[terrytangyuan]

I got this error when running AnomalyDetectionVec():

Error in stl(ts(data[[2L]], frequency = num_obs_per_period), s.window = "periodic",  : 
              series is not periodic or has less than two periods

which is triggered from running this stl(ts(c(2,4,5,5,4,3)), s.window = "periodic")

It looks like this vector needs to be periodic? Any workaround for this? Let me know and I might be able to help you make changes in the code.

Thanks, Yuan
