title: How I do to obtain the solution for Random Effects using package lme4?
body: <p>I have a model similar to this:</p>
  
  <pre><code>model=lmer(y ~ (1|ID) + Factor.A + Factor.B, data=df)
  </code></pre>
  
  <p>I would like to obtain the solution of random effects, but I only could obtain the solution of fixed effects, using this codes:</p>
  
  <pre><code>coef(summary(model))
  summary(model)
  </code></pre>
  
  <p>I tried this code too:</p>
  
  <pre><code>coef(model)
  </code></pre>
  
  <p>but I suppose this output is not for the solution of random effects. Is there a code to obtain the solution of random effects using the package lme4 or another one?</p>
