xtable: Partition crosstable with empty clusters

Description

This produces a crosstable between two integer vectors (partitions) of the same length with a given maximum vector entry k so that the size of the table is k*k with zeroes for missing entries between 1 and k (the command table does pretty much the same thing but will leave out missing entries).

Usage

xtable(c1,c2,k)

Value

A matrix of dimensions c(k,k). Entry [i,j] gives the number of places in which c1==i & c2==j.

Arguments

c1

vector of integers.

c2

vector of integers of same length as c1.

k

integer. Must be larger or equal to maximum entry in c1 and c2.
