[R-sig-eco] Function twostagechao {vegan}

[Peter Solymos]

Dear Diogo,

Thanks for self-correction, I reply for clarification.

The twostagechao function was in the developmental version of vegan
but got removed on 2009-12-16 07:12:59 +0100 (Wed, 16 Dec 2009) at
revision 1083 along its documentation. It never went into vegan stable
release. The function was dropped due to ambiguous interpretation of
double summation in Eqn 12b of Chao et al. 2008 Biometrics 64,
1178--1186. Thus the developmental version of the function was
probably incorrect, therefore I would warn against using it even if
one can dig it out from R-Forge.

Best,

Peter
