Correlation analysis

Description

Correlation analysis

Usage

corranalysis(data, threshold = 0, sig.level = 0.95)

Arguments

data	a numeric matrix or data frame (see cor).
threshold	numeric, correlation cutoff (default 0); correlations in absolute value below threshold are set to 0.
sig.level	numeric, significance level (default 0.95); correlations with p-values greater that 1-sig.level are set to 0.

Value

A list with the following elements:

• corr.mtx (the complete correlation matrix)

• corr.mtx.trunc (the truncated correlation matrix)

• cor.mtest (the output of the significance test on correlations; see cor.mtest)

• threshold correlation cutoff

• sig.level significance level

data <- subset(data, Pbox$MIN >= 500)
out <- corranalysis(data, threshold = 0.5)
