R help - May 2015 - Rgraphviz and NA indices error

Hello,


I ran into the same error. From what I understood, if the code :



        plot(dtm, terms=findFreqTerms(dtm, lowfreq=100) [1:30],
        corThreshold=0.75)

gives you this message it's because there aren't 30 terms which happens
at least a hundred times in your corpus.
Therefore you might want to lower the frequency threshold.

Ylove.
