Description

Visualize a Correlation Matrix with an Hierarchical Tree using ggplot2

Usage

ggcortree(
  x,
  y = NULL,
  k = NULL,
  circular = F,
  nudge = 0.05,
  expand = 0.2,
  label.size = 3.5
)

Arguments

x	a matrix of pairwise correlation among features
y	vector of correlation of the features represented in x with a target quantity. Default is NULL which means that this information is not exploited. If y is supplied it is used to reorder the hierarchical tree under the constrains of its structure.
k	an integer. Number of cluster to cut the tree into. Default is NULL. k is estimate as the minimal number of clusters the would result in an isolated feature.
circular	should the tree be represent in polar coordinates? Default F
nudge	a numeric. Displacement factor of the labels. Aesthetics purpose.
expand	a numeric. Expansion of the y-axis. Aesthetics purpose.
label.size	a numeric. Size of the terminal nodes of the tree labels.
