This function is an R interface for dnapars in the PHYLIP package (Felsenstein 2013). dnapars can be used for MP phylogeny estimation from DNA sequences (Eck & Dayhoff 1966; Kluge & Farris 1969; Fitch 1971).
an object of class
path to the executable containing dnapars. If
optional arguments to be passed to dnapars. See details for more information.
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
nsave number of trees to save if multiple equally parsimonious trees are found (defaults to
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);
transversion logical value indicating whether to use transversion parsimony (defaults to
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).

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