as.splits: Splits representation of graphs and trees.

Description

as.splits produces a list of splits or bipartitions.

Usage

as.splits(x, ...)
"as.splits"(x, ...)
"as.splits"(x, ...)
"print"(x, maxp = getOption("max.print"), zero.print = ".",  one.print = "|", ...)
"as.prop.part"(x, ...)    
compatible(obj)
allSplits(k, labels = NULL)
allCircularSplits(k, labels = NULL)
write.nexus.splits(obj, file = "", weights=NULL, taxa=TRUE, append=FALSE)
read.nexus.splits(file)
addTrivialSplits(obj)
distinct.splits(...)

Arguments

x
An object of class phylo or multiPhylo.
maxp
integer, default from options(max.print), influences how many entries of large matrices are printed at all.
zero.print
character which should be printed for zeros.
one.print
character which should be printed for ones.
...
Further arguments passed to or from other methods.
obj
an object of class splits.
k
number of taxa.
labels
names of taxa.
file
a file name.
weights
Edge weights.
taxa
logical. If TRUE a taxa block is added
append
logical. If TRUE the nexus blocks will be added to a file.

Value

as.splits returns an object of class splits, which is mainly a list of splits and some attributes. Often a splits object will contain attributes confidences for bootstrap or Bayesian support values and weight storing edge weights. read.nexus.splits and write.nexus.splits allow to exchange a splits object with other software like Splitstree.compatible return a lower triangular matrix where an 1 indicates that two splits are incompatible.
