rstack: Produces a Stacked Table With Correlations

Description

Pearson's product-moment coefficient is the well known degree to which two or more variables are linearly associated. In a two-dimensional table, the degree of correlation among the variables is quantified by the correlation coefficient.

Usage

rstack(m)

Arguments

m

is a square matrix.

Value

• An table or a data.frame containing the correlations for m.

encoding

UTF-8

Details

The function generates a flatten table of correlations. Using it beside r2tex will produce a latex-like correlation table. If necessary, typing cor(t(x)) will coerce x to a properly square matrix format.
