title: glmmTMB with beta family
body: <p>I am trying to model the photosynthetic response (fvfm) that takes values from 0 to 0.7, I am using the beta distribution since I have zero inflation, and I consider a dispersion model because my values move away from the average as they pass days, but when running this model: </p>
  
  <pre><code>beta7&lt;-glmmTMB(fvfm~Temperature*dia+(1|ID), zi=~1, disp=~dia, data=ds, family=beta_family(link="logit"))
  </code></pre>
  
  <p>and this appears : </p>
  
  <pre><code>Error in eval(family$initialize) : y values must be 0 &lt; y &lt; 1
  </code></pre>
  
  <p>I add to all the values of my response variable 0.001, so I no longer have zero inflation and the model works.
  This is correct?? or is there any way to run without adding 0.001??
  Thank you!!
