R help - Jul 2007 - Question about cmdscale function

Hi. 

I know matrices that use distances between places works fine when using
cmdscale. However, what about matrices such as: 

  A     B   C   D   E 
A 0    1   23  12  9 
B 1    0   10  12  3 
C 23  10   0   23  4 
D 12  12  23  0   21 
E  9   3    4   21   0 

i.e. matrices which do not represent physical distances between places (as
they would not make sense for real distances such as the one above) but
other statistics instead? 

Thanks

 

Andy
