的R - 错误写入CSV
我有以下数据集时:的R - 错误写入CSV
Artist Song.Rank   Song.Title  Word WordCount SentimentScore.text SentimentScore.sentiment 1 Placeholder  60 More Placeholders alright  40    alright     Neutral 
2 Placeholder  60 More Placeholders  bad  79     bad     Negative 
3 Placeholder  60 More Placeholders  bad  192     bad     Negative 
4 Placeholder  60 More Placeholders better  125    better     Positive 
5 Placeholder  60 More Placeholders  brand  24    brand     Neutral 
6 Placeholder  60 More Placeholders  break  106    break     Negative 
7 Placeholder  60 More Placeholders  cause  18    cause     Neutral 
8 Placeholder  60 More Placeholders  come  59    come     Neutral 
此数据集存在从XLSX文件中的数据。只有最后一列Sentiment是我使用RSentiment软件包自己添加的。
当试图将其插入到一个CSV,我得到以下信息:
> write.csv(dataset,"calculated.csv") Error in if (inherits(X[[j]], "data.frame") && ncol(xj) > 1L) X[[j]] <- as.matrix(X[[j]]) : 
missing value where TRUE/FALSE needed 
了一些研究之后,我发现,这是因为我的数据集包含嵌套数据框,但建议的解决方案Like This没有帮助。 (在这种情况下,我得到了invalid subscript type 'closure'错误。)
编辑:我看了很多帖子这个地方有人问:
> str(dataset) 'data.frame': 28 obs. of 6 variables: 
$ Artist  : chr "Placeholder" "Placeholder" "Placeholder" "Placeholder" ... 
$ Song.Rank  : num 60 60 60 60 60 60 60 60 60 60 ... 
$ Song.Title : chr "More Placeholder" "More Placeholder" "More Placeholder" "More Placeholder" ... 
$ Word   : chr "alright" "bad" "bad" "better" ... 
$ WordCount  : num 40 79 192 125 24 106 18 59 138 146 ... 
$ SentimentScore:'data.frame': 28 obs. of 2 variables: 
    ..$ text  : Factor w/ 23 levels "alright","bad",..: 1 2 2 3 4 5 6 7 8 9 ... 
    ..$ sentiment: Factor w/ 3 levels "Negative","Neutral",..: 2 1 1 3 2 1 2 2 2 2 ... 
回答:
我假设在这里你不想嵌套data.frames。然后就这样做:
new_dataset <- data.frame(subset(dataset, select = -c(SentimentScore)),           dataset$SentimentScore) 
write.csv(new_dataset, 
      file = "dataset.csv", 
      quote = FALSE)
