Rrestdist: R interface for restdist

In Rphylip: An R interface for PHYLIP

Description

This function is an R interface for restdist in the PHYLIP package (Felsenstein 2013). restdist can be used to estimate the evolutionary distances between populations based on restriction site or fragment data.

Usage

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

Arguments

X	an object of class "rest.data" containing data for restriction sites.
path	path to the executable containing restdist. If path = NULL, the R will search several paths for restdist. See details for more information.
...	optional arguments to be passed to restdist. See details for more information.

Details

Optional arguments include the following: quiet suppress some output to R console (defaults to quiet = FALSE); method, the method for calculating the genetic distance - options are "Modified" (the default), and "Nei/Li" (Nei & Li 1979); data, the type of data - either "sites" or "fragments"; gamma alpha shape parameter of a gamma model of rate heterogeneity among sites (defaults to no gamma rate heterogeneity); kappa transition:transversion ratio (defaults to kappa = 2.0); site.length the restriction site length (defaults to site.length=6); and cleanup remove PHYLIP input & output files after the analysis is completed (defaults to cleanup = TRUE).

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

Value

This function returns an object of class "dist".
