findAssocs() is not working, as is seen below. "Lucid" and
"dreaming" occur together quite often in the book.
The corpus is a single document, the text version of a book.? Does this function
require at least two documents?? If so, if I split the book in half will I get
the correlations regarding the book as a whole, or in regards to how the two
halves compare to each other?> docs <- tm_map(docs, stemDocument)
> dtm <- DocumentTermMatrix(docs)
> freq <- colSums(as.matrix(dtm))
> ord <- order(freq)
> freq[tail(ord)]
