The error says there is a problem with the formula used. Did you use a
formula to fit the model? If so, care to show it to us?

Dear List,
I'm trying select spatial variables with ordiR2step function {vegan}.
But I got the following error:
Error in terms.formula(formula, data = data) :
invalid model formula in ExtractVars
Could someone help me with this error? Would be some wrong with structure of
my data?
Thanks in
