Summary Version v0.1.2 of my R package kgrams was just accepted by CRAN. This package provides tools for training and evaluating k-gram language models in R, supporting several probability smoothing techniques, perplexity computations, random text generation and more. Short demo

library(kgrams)
# Get k-gram frequency counts from Shakespeare's "Much Ado About Nothing"
freqs <- kgram_freqs(kgrams::much_ado, N = 4)

# Build modified Kneser-Ney 4-gram model, with discount parameters D1, D2, D3.
mkn <- language_model(freqs, smoother = "mkn", D1 = 0.25, D2 = 0.5, D3 = 0.75)

# Sample sentences from the language model at different temperatures
set.seed(840)
sample_sentences(model = mkn, n = 3, max_length = 10, t = 1)

[1] "i have studied eight or nine truly by your office [...] (truncated output)"
[2] "ere you go : <EOS>"                                                        
[3] "don pedro welcome signior : <EOS>"

sample_sentences(model = mkn, n = 3, max_length = 10, t = 0.1)

[1] "i will not be sworn but love may transform me [...] (truncated output)" 
[2] "i will not fail . <EOS>"                                                
[3] "i will go to benedick and counsel him to fight [...] (truncated output)"

sample_sentences(model = mkn, n = 3, max_length = 10, t = 10)
