title: Loading the readr Package
body: <p>When I try to load <code>readr</code> using the <code>library()</code> function, I get the following error:</p>
  
  <pre><code>Error in loadNamespace(j &lt;- i[[1L]], c(lib.loc, .libPaths()), versionCheck = vI[[j]]) : 
    there is no package called ‘Rcpp’
  In addition: Warning message:
  package ‘readr’ was built under R version 3.3.2 
  Error: package or namespace load failed for ‘readr’
  </code></pre>
  
  <p>I am relatively new to R.  So I am not sure how to interpret this error message.  Can you please show me how I can successfully load <code>readr</code>?</p>
  
  <p>Thanks</p>
