tm에서 content_transformer를 찾을 수 없습니다

Question

content_transformer 함수가 tm 패키지에서 제거되었습니다 0.6-2 ??

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

Answer 1

패키지를 업데이트해야 할 수 있습니다. This GitHub repository은 함수가 내보내 졌음을 나타내며 present in the code입니다.
