This function is an R interface for neighbor in the PHYLIP package (Felsenstein 2013). neighbor can be used for neighbor-joining (Saitou & Nei 1987) and UPGMA (Sokal & Michener 1958) phylogeny inference.
a distance matrix as an object of class
path to the executable containing neighbor. If
optional arguments to be passed to neighbor. See details for more information.
Optional arguments include the following:
quiet suppress some output to R console (defaults to
quiet = FALSE);
method - can be
"nj" (for neighbor-joining), or
"UPGMA" (for UPGMA);
random.order add taxa to tree in random order (defaults to
random.order = TRUE);
outgroup outgroup if outgroup rooting of the estimated tree is desired (only works for
method = "NJ", UPGMA trees are already rooted); and
cleanup remove PHYLIP input & output files after the analysis is completed (defaults to
cleanup = TRUE).
More information about the neighbor program in PHYLIP can be found here http://evolution.genetics.washington.edu/phylip/doc/neighbor.html.
Obviously, use of any of the functions of this package requires that PHYLIP (Felsenstein 1989, 2013) should first be installed. More information about 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 NJ or UPGMA tree.
