Rphylip (version 0.1-23)

Rpars: R interface for pars

Description

This function is an R interface for pars in the PHYLIP package (Felsenstein 2013). pars can be used for MP phylogeny estimation from DNA sequences (Eck & Dayhoff 1966; Kluge & Farris 1969; Fitch 1971).

Usage

Rpars(X, path=NULL, ...)

Arguments

X

an object of class "phylip.data" with a set of binary or multistate characters; or a matrix.

path

path to the executable containing pars. If path = NULL, the R will search several commonly used directories for the correct executable file.

...

optional arguments to be passed to pars. See details for more information.

Value

This function returns an object of class "phylo" that is the optimized tree.

Details

Optional arguments include the following: quiet suppress some output to R console (defaults to quiet = FALSE); tree object of class "phylo" - if supplied, then the parsimony score will be computed on a fixed input topology; thorough logical value indicating whether to conduct a more thorough search (defaults to thorough=TRUE); nsave number of trees to save if multiple equally parsimonious trees are found (defaults to nsave=10000); random.order add taxa to tree in random order (defaults to random.order = TRUE); random.addition number of random addition replicates for random.order = TRUE (defaults to random.addition = 10); threshold threshold value for threshold parsimony (defaults to ordinary parsimony); weights vector of weights of length equal to the number of columns in X (defaults to unweighted); outgroup outgroup if outgroup rooting of the estimated tree is desired; and cleanup remove PHYLIP input & output files after the analysis is completed (defaults to cleanup = TRUE).

More information about the pars program in PHYLIP can be found here http://evolution.genetics.washington.edu/phylip/doc/pars.html.

Obviously, use of any of the functions of this package requires that PHYLIP (Felsenstein 1989, 2013) should first be installed. Instructions for installing PHYLIP can be found on the PHYLIP webpage: http://evolution.genetics.washington.edu/phylip.html.
