R help - Nov 2017 - NEED HELP : Association in single DTM

I have free text data in a single text document. I create a corpus, and
then a document term matrix out of it. I can create a word cloud too.

But when I do word association for the same, using "findAssocs(), it always
returns numeric(0).

EX : findAssocs(dtm, "king" ,000000000000000000000.1)

I read on stack overflow that it is because I have a single document.

What is the workaround for the same ?

If you consider the definition of a DTM, and that findAssoc() computes
associations between words as correlations across documents(!), you will realize
that you can't what you want from a single document. Indeed, what kind of an
"association" would you even be looking for?

Hi Boris,

In that case, if I have lot of free text data (let us assume part of an
Election speech) in one single TEXT document, and i want to find the
association of the top 3 most frequently occurring words with the other
words in the speech, what method do I adopt ?
