Hello, I have problems with my R.
I use package fpp3, but whenever I try to plot seasonal data using gg_season or gg_subseries, I always get this error message:
Error in exists(scale_fn, parent.frame(), mode = "function") :
first argument has length > 1
I tried using my own data and data from the textbook (Forecasting: Principles and Practice (3rd ed)), but I still got the error message.
Could you please help me find the cause of this problem?
