Creating an AIC model selection table with model included
Solution 1:
Just to clarify for those interested in this question, I simply needed add width.cutoff=100L to the mnames line of code.
# create formula-like model names:
mnames <- apply(res[, i], 1, function(x)
deparse(simplify.formula(reformulate(v[!is.na(x)], response = response)), width.cutoff = 100L))
It now works perfectly
