title: package car unable to load, wrong version of nlme
body: <p>When I try to load the 'car' package I get this error:</p>
  
  <pre><code>library(car)
  
  Error in loadNamespace(j &lt;- i[[1L]], c(lib.loc, .libPaths()), versionCheck = vI[[j]]) : 
    namespace 'nlme' 3.1-122 is already loaded, but &gt;= 3.1.123 is required
  Error: package or namespace load failed for 'car'
  </code></pre>
  
  <p>But when I run <code>update.packages()</code> there is nothing to update. I'm using MRO 3.2.3 if that matters.</p>
