as.vector（x，mode）出错：无法强制类型＆＃39;环境＆＃39;矢量类型＆＃39;任何＆＃39;在r工作室

Question

我对推文进行情感分析，并将所有分析的数据绑定到数据框 bayes_final

执行以下代码后，错误为：

Error in as.vector(x, mode) : 
  cannot coerce type 'environment' to vector of type 'any'

这是代码，

library(sentiment)

bayes_final<-
data.frame(text=character(),emotion=character(),polarity=character(),stringsAsFactors=FALSE)

for (incremented_city_value in 1:cities_length) {

  # # using sentiment package to classify emotions

  bayes_emotions <- classify_emotion(tweets[[incremented_city_value]], algorithm='bayes')


  # # # # using sentiment package to classify polarities

  bayes_polarities = classify_polarity(tweets[[incremented_city_value]], algorithm='bayes')

  bayes_df_polarity = data.frame(text=tweets[[incremented_city_value]], emotion=bayes_emotions[,'BEST_FIT'], polarity=bayes_polarities[,'BEST_FIT'], stringsAsFactors=FALSE)

  bayes_final <- rbind(bayes_final,bayes_df_polarity)

}
