correlationPreservation: Preservation of eigengene correlations

In WGCNA: Weighted Correlation Network Analysis

Preservation of eigengene correlations

Description

Calculates a summary measure of preservation of eigengene correlations across data sets

Usage

correlationPreservation(multiME, setLabels, excludeGrey = TRUE, greyLabel = "grey")

Arguments

multiME	consensus module eigengenes in a multi-set format. A vector of lists with one list corresponding to each set. Each list must contain a component data that is a data frame whose columns are consensus module eigengenes.
setLabels	names to be used for the sets represented in multiME.
excludeGrey	logical: exclude the 'grey' eigengene from preservation measure?
greyLabel	module label corresponding to the 'grey' module. Usually this will be the character string "grey" if the labels are colors, and the number 0 if the labels are numeric.

Details

The function calculates the preservation of correlation of each eigengene with all other eigengenes (optionally except the 'grey' eigengene) in all pairs of sets.

Value

A data frame whose rows correspond to consensus module eigengenes given in the input multiME, and columns correspond to all possible set comparisons. The two sets compared in each column are indicated in the column name.
