kmer

K-mer counting and clustering for biological sequence analysis

kmer is an R package for rapidly computing distance matrices and clustering large sequence datasets using fast alignment-free k-mer counting and recursive k-means partitioning.

Installation

To download kmer from CRAN and load the package, run

install.packages("kmer")
library("kmer")

To download the development version from GitHub, first ensure a C/C++ compliler is available and the devtools R package is installed. Linux users will generally have a compiler installed by default; however Windows users may need to download Rtools and Mac OSX users will need Xcode (note that these are not R packages). To download and install devtools, run

install.packages("devtools")

The kmer package can then be installed and loaded by running

devtools::install_github("shaunpwilkinson/kmer") 
library("kmer")

An overview of the package and its functions can be found by running
