Hi Team,
I am creating an n-gram analysis on a text mining data however receiving the error as:-
Error in .jcall("RWekaInterfaces", "[S", "tokenize", .jcast(tokenizer, :
java.lang.NullPointerException
I have used the function:
Ngramtok= function(x)NGramTokenizer(x, Weka_control(min=1, max=5))
and then using this as below:-
ngram1= DocumentTermMatrix(cnt_reason,control = list(tokenize= Ngramtok)).
Checked stack overflow for the error here - http://stackoverflow.com/questions/38605088/creating-ngrams-in-r where it was advised to remove the blank rows but it did not help.
I have strangely used this earlier but it now not working now.
Please suggest.
