Unable to access/install xts package
<p>I am unable to install xts package on R version 3.3.0 on my macbook. I am getting following error:</p>

<blockquote>
  <p>install.packages("xts", repos="http://R-Forge.R-project.org")</p>
  
  <p>Warning: unable to access index for repository <a href="http://R-Forge.R-project.org/bin/macosx/mavericks/contrib/3.3" rel="nofollow">http://R-Forge.R-project.org/bin/macosx/mavericks/contrib/3.3</a>:
    cannot open URL '<a href="http://R-Forge.R-project.org/bin/macosx/mavericks/contrib/3.3/PACKAGES" rel="nofollow">http://R-Forge.R-project.org/bin/macosx/mavericks/contrib/3.3/PACKAGES</a>'</p>
  
  <p>Warning message:
  package ‘xts’ is not available (for R version 3.3.0) </p>
</blockquote>

<p>I also tried installing through "Package Installer" and it seems to have installed with no error/warning. However when I tried following:</p>

<blockquote>
  <p>xts(rnorm(231),as.Date(13514:13744,origin="1970-01-01"))</p>
  
  <p>Error: could not find function "xts"</p>
</blockquote>

<p>Any help is much appreciated.</p>
