This package contains tools for extraction and analysis of various n-grams (sequences of n items) derived from biological sequences (proteins or nucleic acids). To deal with the curse of dimensionality of the n-grams, biogram uses Quick Permutation Test (QuiPT) for fast feature filtering.

biogram is available on CRAN, so installation is as simple as:

install.packages("biogram")

You can install the latest development version of the code using the devtools R package.

# Install devtools, if you haven't already.
install.packages("devtools")
