我正在研究R项目。在尝试分析情绪时，我不得不创建一个数据框（在我的前面，它是“sentiment.df”）。
sentiment.df <- data.frame(text, emotion=emotion, polarity=polarity, stringsAsFactors=FALSE)
此处，文本 - 包含已处理（已清理）推文的列表，这些推文已拆分为关键字;情感 - 包含一堆人物情感;极性 - 包含+ ve，-ve评论家。运行上面的LOC时，我的RStudio引发了以下错误：
Error in data.frame(c("httpstcoux1aacnxbk", "endalz"), c("i", "have", :
arguments imply differing number of rows: 2, 5, 19, 7, 1, 11, 4, 6, 9, 3, 13, 17, 8, 10, 24, 21, 15, 12, 25, 16, 20, 23, 18, 28, 14, 22, 26, 27, 30, 31, 29, 35
这三个变量的长度 - 文本，情感和极性都相同：2621
这就是我的数据：

当我在网上发布此错误时，程序员会说行数和行数。 cols不一样。即，它不是方形矩阵，Dataframe不适用于矩形矩阵。
如果有人帮助我摆脱这个错误，我将不胜感激。
提前致谢！

“文本”中有2621个列表，但文本条目的数量不同。 每个列表可以包含不同数量的单词。 因此即使是unlist（）也不会帮助你，因为所有单词的数量都大于'情绪'和'极性'向量中的条目数。
