Rpenny(X, path=NULL, ...)"phylip.data" with a binary character; or a matrix. Data should be "0", "1", and "?".path = NULL, the R will search several commonly used directories for the correct executable file."phylo" or "multiPhylo" that is the tree or trees with the best parsimony score. tree$score gives the parsimony score, for "phylo" object tree.
quiet suppress some output to R console (defaults to quiet = FALSE); mixture, a vector containing "W" and "C" in upper or lower case indicating which characters should be evaluated using Wagner (Eck & Dayhoff 1966; Kluge & Farris 1969) or Camin-Sokal (Camin & Sokal 1965) parsimony methods, respectively - this argument takes precedence over method (see below); method either "Wagner" or "Camin-Sokal", in upper or lower case, indicating whether Wagner (Eck & Dayhoff 1966; Kluge & Farris 1969) or Camin-Sokal (Camin & Sokal 1965) parsimony should be used; groups number of groups of 1,000 trees (defaults to groups = 100); report reporting frequency, in numbers of trees (defaults to report = 1000); simple simple branch & bound (defaults to simple = TRUE); threshold threshold value for threshold parsimony (defaults to ordinary parsimony); ancestral a vector of length equal to the number of columns in X containing the the ancestral state at the root of the tree for each character, these should be "0", "1", and "?"; 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).More information about the penny program in PHYLIP can be found here http://evolution.genetics.washington.edu/phylip/doc/penny.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.
