title: Cant install psych package
body: <p>I am new to R-studio and I am trying to install the <code>psych</code> package but I get the following error:</p>
  <pre><code>&gt; Error: package or namespace load failed for ‘psych’ in loadNamespace(j
  &gt; &lt;- i[[1L]], c(lib.loc, .libPaths()), versionCheck = vI[[j]]):  there
  &gt; is no package called ‘mnormt’
  </code></pre>
  <p>So then I tried to install the <code>mnormt</code> package and I get the following message:</p>
  <pre><code>&gt; package ‘mnormt’ successfully unpacked and MD5 sums checked Warning in
  &gt; install.packages :   cannot remove prior installation of package
  &gt; ‘mnormt’ Warning in install.packages :   restored ‘mnormt’
  </code></pre>
  <p>But when I then try to install the <code>psych</code> package it keeps saying that the <code>mnormt</code> package was not installed.</p>
