This function is an R interface for threshml in the PHYLIP package (Felsenstein 1989, 2013). threshml fits the threshold model of Felsenstein (2005; 2012). Note that threshml is new & not in the currently released version of PHYLIP (as of December 2013). It can be downloaded from its webpage here: http://evolution.gs.washington.edu/phylip/download/threshml/. If not specifying path
, the executable file for threshml (e.g., threshml.exe in Windows) should be placed in the folder containing all other executable files for PHYLIP (e.g., C:/Program Files/phylip=3.695/exe in Windows).
Obviously, use of any of the functions of this package requires that PHYLIP (Felsenstein 2013) should first be installed. More information about installing PHYLIP can be found on the PHYLIP webpage: http://evolution.genetics.washington.edu/phylip.html.

a data.frame of continuous valued or discrete character traits with rownames containing species names. Discrete & continuous characters can be supplied in any order. All discrete character traits must be two-state, but can be coded using any convention (i.e., |

optional arguments to be passed to threshml. See details for more information. |
Optional arguments include the following: quiet
suppress some output to R console (defaults to quiet = FALSE
); burnin
burnin generations for the MCMC; nchain
number of chains of the MCMC; ngen
number of generations in each chain; proposal
variance on the proposal distribution for the MCMC; lrtest
logical value indicating whether to conduct a likelihood-ratio test of the hypothesis that some correlations are zero (does not appear to work in the present version); and cleanup
remove PHYLIP input/output files after the analysis is completed (defaults to cleanup = TRUE
).
This function returns a list containing the results from threshml.
