title: Error loading ggplot2 in RStudio
body: <p>I saw a version of this question posted, but still did not see the answer. I am trying to use ggplot2 but get the following errors</p>
  
  <pre><code>Error in loadNamespace(i, c(lib.loc, .libPaths()), versionCheck = vI[[i]]) : 
    there is no package called ‘stringi’
  Error: package or namespace load failed for ‘ggplot2’
  </code></pre>
  
  <p>I installed stringi - leading to this error</p>
  
  <pre><code>There is a binary version available but the source version is
  later:
          binary source needs_compilation
  stringi  0.5-2  0.5-5              TRUE
  
    Binaries will be installed
   trying URL 'http://cran.rstudio.com/bin/windows/contrib/3.2/stringi_0.5-2.zip'
  Warning in install.packages :
   cannot open: HTTP status was '404 Not Found'
  Error in download.file(url, destfile, method, mode = "wb", ...) : 
   cannot open URL    'http://cran.rstudio.com/bin/windows/contrib/3.2/stringi_0.5-2.zip'
  Warning in install.packages :
    download of package ‘stringi’ failed
  </code></pre>
  
  <p>Then I read this question - <a href="https://stackoverflow.com/questions/31038636/package-stringi-does-not-work-after-updating-to-r3-2-1">package &#39;stringi&#39; does not work after updating to R3.2.1</a>. And followed the suggestion of using the option and getting binaries for my windows version</p>
  
  <pre><code>&gt; options(install.packages.check.source = "no")
  &gt; install.packages("stringi",type="win.binary")
  trying URL 'http://cran.rstudio.com/bin/windows/contrib/3.2/stringi_0.5-2.zip'
  Warning in install.packages :
    cannot open: HTTP status was '404 Not Found'
  Error in download.file(url, destfile, method, mode = "wb", ...) : 
    cannot open URL 'http://cran.rstudio.com/bin/windows/contrib/3.2/stringi_0.5-2.zip'
  Warning in install.packages :
    download of package ‘stringi’ failed
  </code></pre>
  
  <p>And now my analysis is stuck just because of this; no ggplot2. </p>
