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)

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.

Value

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

  c1 <- 1:3
  c2 <- c(1,1,2)
  xtable(c1,c2,3)
