Error in if (is.na(beta)) {: argument is of length zero #4
Description
When using a monthly data from 2016 to 2018 and forcing the model to be "ZAA", the following error occurs.
mapa(test, model="ZAA")
Error in if (is.na(beta)) { : argument is of length zero
I understand that it might mean that there's no beta/trend detected, but ETS(test, model="ZAA") alone is able to produce something. There must be a way to fix this error.
Looking forward to your update. Thanks.
