我正在使用tm包来应用词干,我需要将结果数据转换为数据帧.可以在这里找到解决方案R tm package vcorpus:将语料库转换为数据帧时出错,但在我的情况下,我将语料库的内容作为:
[[2195]]
i was very impress
代替
[[2195]]
"i was very impress"
因此,如果我申请
data.frame(text=unlist(sapply(mycorpus, `[`, "content")), stringsAsFactors=FALSE)
结果将是
<NA>.
任何帮助深表感谢!
以下代码为例:
sentence <- c("a small thread was loose on the sandals, otherwise it looked good")
mycorpus <- Corpus(VectorSource(sentence))
mycorpus <- tm_map(mycorpus, stemDocument, language = "english")
inspect(mycorpus)
[[1]]
a small thread was loo on the sandals, otherwi it look good
data.frame(text=unlist(sapply(mycorpus, `[`, "content")), stringsAsFactors=FALSE)
text
1 <NA>
