Dear all,

 

I am desperately searching for code lines able to modify the standard outputs of CCA in Vegan. I need to have an access to the three parameters U, C and T, usually employed for unimodal species response curves:

U : centre of species distributions (species scores) is presently given but

C : species maximal theoretical abundance, named Ť N2 ť in 'old' Canoco outputs and

T : "species tolerance" on each axis = (the range of species occurrences is 4T).

 

..are lacking

 

It would be helpful if anyone knew the syntax required

 

Best regards

Dominique
