Description

Keeps only the specified labels i and j and returns the data from classes with these labels and also the corresponding label vector having class labels i and j only.

Usage

pairwise.lab(dat, lab, i, j)

Arguments

dat	The data set in one or higher dimensions, each row corresponds to a data point.
lab	The vector of class labels (numerical or categorical)
