[R-sig-eco] Distance matrix analyses

[Diego Javier Inclan Luna]

Hi,

I would like to test dissimilarities among different groups in a dist
matrix. For instance, if I have a dist matrix with three factors a, b, c,
functions like adonis and betadisper in vegan will test the aa, bb and cc
combinations. However, I am interested in testing the ba, ca, and cb
combinations. How I could test for these combinations?


*a  a   a   b   b   b   c   c  c*

*a* aa
*a* aa aa
*a* aa aa aa
*b* ba ba ba bb
*b* ba ba ba bb bb
*b* ba ba ba bb bb bb
*c* ca ca ca cb cb cb cc
*c* ca ca ca cb cb cb cc cc
*c* ca ca ca cb cb cb cc cc cc


Thanks!
