Dear all,

is it possible to run a model selection with ordistep on a partialRDA?

I have three matrices of variables: xvars, yvars and zvars.

I can't find a way to tell ordistep I want to condition every RDA by all the
variables in zvars before testing variables in xvars. What ordistep seems to
be doing at the moment is testing the significance of 'xvars' as a single
term.

Any ideas?

Thanks in advance for your replies.

Mariano
