title: Issues installing data.table in R 3.6.3 (Oct 2020)
body: <p>I'm using a Mac with OS Sierra 10.12.5. I'm having trouble with installing the R package &quot;data.table,&quot; including if I try to install via install.packages(&quot;Hmisc&quot;), or install.packages(&quot;data.table&quot;). Both result in:</p>
  <pre><code>installing to /Library/Frameworks/R.framework/Versions/3.6/Resources/library/00LOCK-data.table/00new/data.table/libs
  ** R
  ** inst
  ** byte-compile and prepare package for lazy loading
  ** help
  *** installing help indices
  ** building package indices
  ** installing vignettes
  ** testing if installed package can be loaded from temporary location
  Error: package or namespace load failed for ‘data.table’ in library.dynam(lib, package, package.lib):
   shared object ‘datatable.so’ not found
  Error: loading failed
  Execution halted
  ERROR: loading failed
  * removing ‘/Library/Frameworks/R.framework/Versions/3.6/Resources/library/data.table’
  
  The downloaded source packages are in
      ‘/private/var/folders/bl/lgd7_j2j087f24tcly84xg580000gn/T/RtmpbM5EaD/downloaded_packages’
  Warning message:
  In install.packages(&quot;data.table&quot;) :
    installation of package ‘data.table’ had non-zero exit status
  </code></pre>
  <p>I then tried installing directly from the .zip at: <a href="https://github.com/Rdatatable/data.table" rel="nofollow noreferrer">https://github.com/Rdatatable/data.table</a>, but got the following &quot;not available for R 3.6.3&quot; message:</p>
  <pre><code>&gt; install.packages(&quot;~/Downloads/data.table-master.zip&quot;)
  Warning message:
  package ‘~/Downloads/data.table-master.zip’ is not available (for R version 3.6.3) 
  </code></pre>
  <p>I tried the approaches in this thread, but none worked :\ : <a href="https://stackoverflow.com/questions/32721775/problems-installing-data-table-for-r/38762586">Problems installing data.table for R</a></p>
  <p>Any advice for what I can try next, or where I can access a version of data.table specifically for R 3.6.3?</p>
