> require(multcomp)
for some reason it is not working but all of the other functions have
work. What does this error mean and how do I fix it?

Error in constants(lhs, cnames_symb) :
The hypothesis "RayosRayos.2 = (Intercept)" is not well formed:

In addition: Warning message:
In constants(lhs, cnames_symb) : NAs introduced by coercion
