title: lib unspecified & Error in loadNamespace
body: <p>I had everything working with R and RStudio, but then I moved the folders when cleaning up my computer directories &amp; files. Now I'm getting the error message below.</p>
  
  <p>Should R and RStudio be installed under <code>Program Files</code> or <code>Program Files (x86)</code>? Should I have two <code>libPaths</code>?</p>
  
  <pre><code>install.packages("C:/Users/kevin/Downloads/fpp_0.5.zip", repos = NULL)
