Subject: Concurrence Matrix

Thank you for all the help.

Can someone refer me to a function that can help with the creation of
a concurrence matrix?

I have two asymmetric vectors (C is length 217 and D is length 16063)
that contain values of 0,1,2

I want to create a matrix E (where rows are D and columns are C)  that
ouputs a score where

if C and D are the same number then E has value 1
if C and D are different numbers (i.e. 0 and 1, or 2 and 1) then E has a value 0

so for example:

so if C is c(0,0,2,1,0,0)
and  D is c(0,0,1,1,1,1,1,1)

E would look like:

      C      0  0  2  1  0  0

D    0      1  1  0  0  0  0  
      0      1  1  0  0  1  1
      1      0  0  0  1  0  0
      1      0  0  0  1  0  0
      1      0  0  0  1  0  0 
      1      0  0  0  1  0  0
      1      0  0  0  1  0  0 
      1      0  0  0  1  0  0
