dimRed (version 0.2.3)

maximize_correlation,dimRedResult-method: Maximize Correlation with the Axes

Description

Rotates the data in such a way that the correlation with the first naxes axes is maximized.

Usage

# S4 method for dimRedResult
maximize_correlation(object,
  naxes = ncol(object@data@data), cor_method = "pearson")

Arguments

object

A dimRedResult object

naxes

the number of axes to optimize for.

cor_method

which correlation method to use

Details

Methods that do not use eigenvector decomposition, like t-SNE often do not align the data with axes according to the correlation of variables with the data. maximize_correlation uses the optimx package to rotate the data in such a way that the original variables have maximum correlation with the embedding axes.
