Warning: Using formula(x) is deprecated when x is a character vector of length > 1. Consider formula(paste(x, collapse = " ")) instead.

Hi all,

I have got this model with all my 6 occupancy variables, plus 2 more for detection.

It turns out that when I try to run it I get an odd warning message:

Using formula(x) is deprecated when x is a character vector of length > 1. Consider formula(paste(x, collapse = " ")) instead.

Here are my lines of code along with the warning message:

However, when I remove the AgriPast covariate, it runs smoothly:

Any ideas of why this may be happening?

Thanks!

This is due to a bug (fixed in the dev version of the package) that appears when the formula is very long. You can ignore it for models, like yours, that don't include random effects.
