Ошибка аргумента arima xreg, вызванная именем столбца во фрейме данных

Я пытаюсь запустить приведенный ниже код и получаю указанную ниже ошибку. Код использует auto.arima из пакета прогнозов для определения и подгонки модели arima к некоторым данным. Он также использует регрессоры в аргументе xreg. Я думаю, что имена двух столбцов в xreg могут быть проблемой, но я не уверен, почему. Имена столбцов похожи на "structure.c.NA..NA..211L ..". Они являются выходными данными функции. Если я запустил auto.arima без этих столбцов в аргументе xreg, похоже, все будет в порядке. Мы очень ценим любые советы о том, как решить эту проблему.

Код:

auto.arima(df2_comb[1:100,names(df2_comb)=='ECDD'], xreg = df2_comb[,names(df2_comb)!='ECDD'][1:100,names(df2_comb[,!names(df2_comb)%in%c('ECDD','order_dts')])])

Ошибка:

Error in auto.arima(df2_comb[1:100, names(df2_comb) == "ECDD"], xreg = df2_comb[,  : 
  xreg should be a numeric matrix or vector

Данные:

dput(df2_comb[1:100,])

## it works
auto.arima(df2_comb[1:100,names(df2_comb)=='ECDD'], xreg = as.matrix(df2_comb[,names(df2_comb)!='ECDD'][1:100,names(df2_comb[,!names(df2_comb)%in%c('ECDD','order_dts')])]))
## it fails
colnames(df2_comb)[3]<- "structure_211"
colnames(df2_comb)[4]<- "structure_48"
auto.arima(df2_comb[1:100,names(df2_comb)=='ECDD'], xreg = df2_comb[,names(df2_comb)!='ECDD'][1:100,names(df2_comb[,!names(df2_comb)%in%c('ECDD','order_dts')])])

Это не связано с именами, как вы можете видеть, если вы измените их, не удастся точно так же. Но если вы используете xreg as.matrix, это должно помочь!

Спасибо! Это помогло. Этот же код отлично работал в прошлом и отлично работал на моем Mac, но имел проблемы на компьютере. Знаете ли вы, были ли недавно внесены изменения в пакет прогнозов? - person user3476463; 18.03.2019
