What algorithm I need to find n-grams?

Question

What algorithm is used for finding ngrams?

Supposing my input data is an array of words and the size of the ngrams I want to find, what algorithm I should use?

Answer 1

For anyone still interested in this topic, there is a package on the cran already.

ngram: An n-gram Babbler

This package offers utilities for creating, displaying, and "babbling" n-grams. The babbler is a simple Markov process.
