How to extract fixed effects part of summary from lme4?
<p>I wish to extract the fixed effects part of <code>summary()</code> as a data.frame. I am using <code>lme4</code> to run the following model:</p>

<pre><code>SleepStudy &lt;- lmer(Reaction ~ Days + (1|Subject), data = sleepstudy)
summary(SleepStudy)
</code></pre>

<p>I know that I can extract the random effects section of <code>summary</code> by using the following:</p>

<pre><code>SleepStudy_RE &lt;- as.data.frame(VarCorr(SleepStudy))
</code></pre>

<p>Is there a similar line of code for the fixed effects, including the estimate, standard error, degrees of freedom and exact p-value?</p>

<p>Thank you.</p>
