Rclique: R interface for clique

Description Usage Arguments Details Value Author(s) References See Also Examples


This function is an R interface for clique in the PHYLIP package (Felsenstein 2013). clique can be used for phylogeny inference using the compatibility method (Le Quesne 1969; Estabrook et al. 1976).


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



an object of class "phylip.data" with a set of binary characters; or a matrix.


path to the executable containing clique. If path = NULL, the R will search several commonly used directories for the correct executable file.


optional arguments to be passed to clique. See details for more information.


Optional arguments include the following: quiet suppress some output to R console (defaults to quiet = FALSE); ancestral vector of ancestral states; weights vector of weights of length equal to the number of columns in X (defaults to unweighted); minimum.clique, if specified, will cause Rclique to print out all cliques (and corresponding trees) greater than minimum.clique; 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).

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


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