This function writes stochastic character mapped trees to file in multiple SIMMAP formats (Bollback 2006).
write.simmap(tree, file=NULL, append=FALSE, map.order=NULL, quiet=FALSE,
format="phylip", version=1.0)an object of class "simmap" or "multiSimmap".
an optional filename.
a logical value indicating whether to append to file.
a optional value specifying whether to write the map in left-to-right or right-to-left order. Acceptable values are "left-to-right" or "right-to-left" or some abbreviation of either. If not provided, write.simmap will use attr(tree,"map.order") if available.
logical value indicating whether or not to print a warning message when map.order is neither specified by a function argument or as an attribute of tree.
file format for output.
version of SIMMAP. Note that the options are 1.0 and 1.5. version=1.5 is generally recommended because in this format the tree can also be parsed by typical tree readers, but absent its mapped trait.
