Dear all, I'd like to introduce a new R package called *phylogram,* for working with evolutionary trees as deeply-nested lists known as "dendrogram" objects.
The package provides functions for importing and exporting phylogenetic trees in the Newick parenthetic text format, as well as several functions for command-line tree manipulation. With an emphasis on speed and computational efficiency, the *phylogram* package also includes tools for rapidly computing distance matrices, and building large trees using fast alignment-free k-mer counting and divisive clustering. While not guaranteed to produce sufficiently accurate phylogenetic trees for taxonomic purposes, this offers an efficient means of clustering large trees for a variety of other applications including tree-based sequence weighting, guide trees for progressive multiple sequence alignment, and other recursive operations such as classification tree learning. Any feedback is warmly welcomed. vignette: https://cran.r-project.org/web/packages/phylogram/vignettes/phylogram-vignette.html development version: https://github.com/shaunpwilkinson/phylogram bug reports: https://github.com/shaunpwilkinson/phylogram/issues google group: https://groups.google.com/group/phylogram Best regards, Shaun Wilkinson Email: shaunpwilkinson at gmail.com Twitter: @wilkinshau [[alternative HTML version deleted]] _______________________________________________ R-packages mailing list r-packa...@r-project.org https://stat.ethz.ch/mailman/listinfo/r-packages ______________________________________________ R-help@r-project.org mailing list -- To UNSUBSCRIBE and more, see https://stat.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide http://www.R-project.org/posting-guide.html and provide commented, minimal, self-contained, reproducible code.
