treePart  R Documentation 
The function treePart
defines partitions of tips reflecting the
topology of a tree. There are two possible outputs (handled by the argument
result
):
 basis
mode: each node but the root is translated
into a dummy vector having one value for each tip: this value is '1' if the
tip descends from this node, and '0' otherwise.
 orthobasis
: in
this mode, an orthonormal basis is derived from the basis previously
mentionned. This orthobasis was proposed in the orthogram (Ollier et
al. 2006).
treePart(x, result = c("dummy", "orthobasis"))
x 
a tree of class 
result 
a character string specifying the type of result: either a
basis of dummy vectors ( 
Orthobasis produced by this function are identical to those stored in the Bscores component of deprecated phylog objects, from the ade4 package.
A matrix of numeric vectors (in columns) having one value for each tip (rows).
