I'm using the NGramTokenizer from the rWeka package. I believe i have installed everything correctly. I'm executing the following code:
Bigram_Tokenizer <- function(x) NGramTokenizer(x, Weka_control(min = 2, max = 2))
tdm <- TermDocumentMatrix(corpus, control = list(tokenize= Bigram_Tokenizer()))
Error I receive is:
Error in lapply(x,f): argument "x" is missing with no default.
Any ideas on how to resolve this? Thanks again in advance.
Best
