Some simple "getters" for ngram objects. Necessary since
the internal representation is not a native R object.
Usage
## S3 method for class 'ngram':
get.ngrams(ng)
## S3 method for class 'ngram':
get.string(ng)
## S3 method for class 'ngram':
get.nextwords(ng)
Arguments
ng
An ngram object.
Details
get.ngrams() returns an R vector of all n-grams.
get.nextwords() does nothing at the moment; it will be
implemented in future releases.
getnstring() recovers the input string as an R string.
