【问题描述】：

是否从 tm 包 0.6-2 中删除了 content_transformer 函数？？

library(tm)
docs<-Corpus(DirSource("Dname"))
docs<-tm_map(docs,content_transformer(gsub), pattern="using",replacement="use")
Error: could not find function "content_transformer"

您可能需要更新软件包。 This GitHub repository表示函数导出，也是present in the code。

function(x, ...) {
    content(x) <- FUN(content(x), ...)
