Error in adonis - right-hand-side of formula has no usable terms

[rbfontana]

Hi,

I'm trying to run a phylogenetic eigenvector regression and selection (PVR.adonis - daee) that uses adonis to this, but for a reason, that I don't know, I'm having an error with adonis.

Error message: "Error in vegan::adonis(traits ~ x[, include.temp, drop = FALSE], permutations = 1) :
right-hand-side of formula has no usable terms"

Does anyone have advice?

You should use a right-hand side that has usable terms.

You should not use formula interface like that. The canonical way is:

## adonis is deprecated: use adonis2 instead
adonis2(traits ~ used.term, data=x) # replace used.term with the name of your variable in x data frame

Your way works, if defined correctly, but errors are more easily made with your interface. For instance you may refer to a non-existing column. What do you see if you issue:

x[, include.temp, drop = FALSE]
