Install R & RTools from Windows terminal
<p>I have a number of people @ work who I'd like to share some R scripts and other assorted goodies.  This requires they have an instance of <a href="https://cran.r-project.org/bin/windows/base/" rel="noreferrer">R</a> and accompanying <a href="https://cran.r-project.org/bin/windows/Rtools/" rel="noreferrer">Rtools</a> up and running and on their path.  Adding something to the path is pretty easy to script but installing R and Rtools from windows command line is not (at least googling "install R from Windows command line" was not productive).</p>

<p>How can I install R and RTools from the windows terminal into the <code>C:\</code> level directory (this can be made into a .bat file for clickable distribution)?</p>
