Question

时间序列预测脚本会返回以下错误：

library(forecast) # version 6.1

myfc = forecast(myts)  # see ts object below
Error in decompose(y, type = switch(seasontype, A = "additive", M = "multiplicative")) : 
  unused argument (type = switch(seasontype, A = "additive", M = "multiplicative"))

我在?forecast中没有看到相关的参数，所以我不知道这个错误来自哪里。该代码以前工作过，我最近更新了我的所有软件包，因此可能与预测软件包的更改有关。

这里是时间序列对象和sessionInfo（）：
