This repo contains data from Ted Kwartler's "Text Mining in Practice With R" book.

In December 2017, the tm package was changed. Specifically, readTabular was removed. For more specifics click here

An example on page 43 of the book no longer works as written but the code below corrects the issue.

• If using DataframeSource the first column MUST be named doc_id followed by a text column. Any other columns are considered metadata associated row-wise.

This makes it easier instead of manually declaring metadata through a readerControl.

#DEPRECATED: 
#tweets<-data.frame(ID=seq(1:nrow(text.df)),text=text.df$text)
tweets<-data.frame(doc_id=seq(1:nrow(text.df)),text=text.df$text)

#DEPRECATED: 
#meta.data.reader <- readTabular(mapping=list(content="text", id="ID"))
#corpus <- VCorpus(DataframeSource(tweets), readerControl=list(reader=meta.data.reader))

corpus <- VCorpus(DataframeSource(tweets))
corpus<-clean.corpus(corpus)
