reorderImage {blockmodeling}

Reordering an image matrix of the blockmodel (or an error matrix based on new and old partition

Description

Reorders an image matrix of the blockmodel (or an error matrix based on new and old partition. The partitions should be the same, except that classes can have different labels. It is useful when we want to have a different order of classes in figures and then also in image matrices. Currently it is only suitable for one-mode blockmodels.

Usage

reorderImage(IM, oldClu, newClu)

Arguments

IM

An image or error matrix.

oldClu

Old partition.

newClu

New partition, the same as the old one except for class labeles.

Value

Reorder matrix (rows and columns are reordred).
