This function is an R interface for fitch in the PHYLIP package (Felsenstein 2013). fitch can be used for tree inference using the Fitch-Margoliash method (Fitch & Margoliash 1967), the Cavalli-Sforza & Edwards leasts-squares method (Cavalli-Sforza & Edwards 1967), and the minimum evolution criterion (Kidd & Sgaramella-Zonta 1971; Nei & Rzhetsky 1993).

optional arguments to be passed to fitch. See details for more information. |
Optional arguments include the following: quiet
suppress some output to R console (defaults to quiet = FALSE
); method
- can be "FM"
or "fm"
(for the Fitch-Margoliash criterion; Fitch & Margoliash 1967), "LS"
or "ls"
for the Cavalli-Sforza & Edwards (1967) least-squares criterion, or "ME"
or "me"
(for Minimum Evolution); tree
object of class "phylo"
- if supplied, then branch lengths are optimized & the optimality criterion is computed on the input tree; negative
a logical value indicating whether negative branch lengths should be permitted (defaults to negative = TRUE
; global
perform global search (defaults to global = TRUE
); 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
); 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. 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 Fitch-Margoliash, LS, or ME tree.
