[R] Reading Multiple Files for Text Mining in R Using TM Package?
Well, you read documents from directory = "D:/Shivi/R Project" and you say that you have 220+ files in this directory If you move respective files into some working directory you could use let say docs<- Corpus(DirSource(directory = "D:/Shivi/R Project/work")) without need to use setwd. But maybe I do not understand your problem corrrectly.
