Description

Display images of the correlation matrices within and between two data matrices.

Usage

img.matcor(correl, type = 1)

Arguments

correl	Correlation matrices as returned by the matcor() function
type	character determining the kind of plots to be produced: either one ((p+q) * (p+q)) matrix or three matrices (p * p), (q * q) and (p * q)
