Plotting post-fitting inference effects in a glmmTMB model

Hello,


I have the next model:

zipoisson2  <- glmmTMB(Observations ~ CAP * Condition + (1|ID), contrasts=list(CAP="contr.sum",Condition="contr.sum"), data=mDATA, ziformula=~ 1 , family=poisson)

Plotting the effects ("effects" package), I obtain:

(ae <- allEffects(zipoisson2))

model: Observations ~ CAP * Condition
 CAP*Condition effect
        Condition
CAP        aapaff      aff      neu     pneu

  preC5  2.184075 2.310564 3.137734 1.995430

plot(ae)
Error in UseMethod("droplevels") :
  no applicable method for 'droplevels' applied to an object of class "character"

Question 1: Has anyone encountered the same issue? Any hint to solve it?

Question 2: Maybe is there any other package works better with glmmTMB model

Thanks in advance for any hint about it.

Julian,
