title: MXNet package installation in R
body: <p>I get plenty of trouble when trying to install <strong>MXNet</strong> package in R
  I am using the 3.4.0 version of R and I am on windows 10 CPU intel i3, 64bits  x64-based processor.</p>
  
  <p>I get prompted:</p>
  
  <pre><code>install.packages("mxnet")
  Warning in install.packages :
    cannot open URL 'http://www.stats.ox.ac.uk/pub/RWin/src/contrib/PACKAGES.rds': HTTP status was '404 Not Found'
  Installing package into ‘C:/Users/los40/OneDrive/Documentos/R/win-library/3.4’
  (as ‘lib’ is unspecified)
  Warning in install.packages :
    package ‘mxnet’ is not available (for R version 3.4.0)
  Warning in install.packages :
    cannot open URL 'http://www.stats.ox.ac.uk/pub/RWin/bin/windows/contrib/3.4/PACKAGES.rds': HTTP status was '404 Not Found'
  </code></pre>
  
  <p>I've tried downloading the .rar files provided here. I decompress one and get the folder where it says "R package" attempting to install it by using:</p>
  
  <pre><code>&gt; install.packages('R.package.rar', lib='D:/mxnet',repos = NULL)
  Error in install.packages : type == "both" cannot be used with 'repos = NULL'
  &gt; install.packages('R.package.rar', lib='D:/mxnet')
  Warning in install.packages :
    package ‘R.package.rar’ is not available (for R version 3.4.0)
  </code></pre>
  
  <p>The guide found in <a href="http://mxnet.io/get_started/windows_setup.html" rel="noreferrer">http://mxnet.io/get_started/windows_setup.html</a> makes no sense to me since I cannot find the file required in the steps for installing the prebuild package on windows called <strong>setupenv.cmd</strong></p>
