Select features that are correlated with a given feature (or one or more features from a set of features).

Description

Select features that are correlated with a given feature (or one or more features from a set of features).

Usage

selectCorrelatedRows(Y, X, corThreshold = 0.1, useAbsCor = TRUE)

Arguments

Y	a vector or matrix; rows from X will be correlated with Y if Y is a vector or with rows of Y, if Y is a matrix.
X	a matrix of values that will be compared with Y (vector) or rows of Y (matrix)
corThreshold	the minimum correlation threshold for the row to be returned
useAbsCor	a logical value indicating whether absolute correlations should be used (default=TRUE).

Value

a matrix of rows of X correlated with Y (if Y is a vector) or correlated with at least one row of Y if Y is a matrix or data frame.

Examples

vec <- runif(10)
mat <- matrix(runif(100), 10, 10)
selectCorrelatedRows(vec, mat)
