tree.weight: Weights based on GSC Tree Method

Description

tree.weight Produce a set of weights for different end points based on a correlation matrix using the GSC tree method

Usage

tree.weight (cor.mat, method="GSC", clustering.method="average", plot=TRUE, 
    orientation=c("vertical","horizontal"), ...)

Value

A vector of weights that sum to 1.

Arguments

cor.mat

a matrix, correlation matrix

method

a string. GSC, implementation of Gerstein et al., is the only implemented currently

clustering.method

a string, how the bottom-up hierarchical clustering tree is built, is passed to hclust as the method parameter

plot

a Boolean, whether to plot the tree

orientation

vertical or horizontal
