: a list which elements gives the path leading from the root to taxonomic units<br />

(leaves and nodes)<br />

: a vector which names corresponds to taxonomic units and values gives distance<br />

between taxonomic units and the root<br />

: call<br />

: a phylogenetic link matrix, generally called the covariance matrix. Matrix<br />

values W mat ij correspond to path length that lead from root to the first common<br />

ancestor of the two leaves i and j<br />

: a phylogenetic distance matrix of class ’dist’. Matrix values W dist ij correspond<br />

to √ d ij where d ij is the classical distance between two leaves i and<br />

j<br />

: a vector with the eigen values of Wmat<br />

: a data frame with eigen vectors of Wmat. This data frame defines an orthobasis<br />

that could be used to calculate the orthonormal decomposition of a biological<br />

trait on a tree.<br />

: a phylogenetic link matrix stemed from Abouheif’s test and defined in Ollier<br />

et al. (submited)<br />

: a vector with the eigen values of Amat<br />

: number of positive eigen values<br />

: a data frame with eigen vectors of Amat. This data frame defines an orthobasis<br />

that could be used to calculate the orthonormal decomposition of a biological<br />

trait on a tree.<br />

: a data frame with attributes associated to nodes.<br />

: a data frame giving for some taxonomic units the partition of leaves that is<br />

associated to its<br />

: a data frame giving an orthobasis defined by Ollier et al. (submited) that could<br />

be used to calculate the orthonormal decomposition of a biological trait on a<br />

tree.<br />

: a vector giving the degree of phylogenetic autocorrelation for each vectors of<br />

Bscores (Moran’s form calculated with the matrix Wmat)<br />

: a vector giving for each nodes the name of the vector of Bscores that is associated<br />

to its<br />
