R Documentation

Write a stochastic character mapped tree to file

Writes one or multiple stochastic character mapped trees to file in several formats (following Bollback, 2006).

write.simmap(tree, file=NULL, append=FALSE, map.order=NULL, quiet=FALSE, 
    format="phylip", version=1.0)

`tree`	an object of class `"simmap"` or `"multiSimmap"`.
`file`	an optional filename.
`append`	a logical value indicating whether to append to file.
`map.order`	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.
`quiet`	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`.
`format`	file format for output.
`version`	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.
