Hi Jim,

Thank you for the reply.

Is there a way out to use it with wordcloud package and built a comparative and commonality cloud. 

My usage: 

comparison.cloud(term.matrix,max.words=300)   commonality.cloud(term.matrix,random.order=FALSE, rot.per=0)

I am already doing a lot of preprocessing and the sentence is not limited to 1 or 2.
