title: package 'stringi' does not work after updating to R3.2.1
body: <p>I saw a <a href="https://stackoverflow.com/questions/30983013/error-in-loadnamespacei-clib-loc-libpaths-versioncheck-vii-the">version of this question</a> posted, but still did not see the answer. I am trying to use ggplot2 but get the following errors (everything worked this morning using R3.0.2 'frisbee sailing' with RStudio version 0.98.1102. </p>
  
  <p>I updated both R and Rstudio and now get the following:</p>
  
  <pre><code>library(ggplot)
  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>So naturally I tried: </p>
  
  <pre><code>&gt; install.packages('stringi')
  
  **There is a binary version available but the source version is later:
      binary source needs_compilation
   stringi  0.4-1  0.5-2             FALSE**

  <p>Any suggestions on how to get 'stringi' to install? I'm not real familiar with the error output. Should I just try to go back to older versions of R and Rstudio? Ultimately I'm worried that this will be the tip of the iceberg in terms of packages now not working with the updated R</p>
  
  <p>oh and:</p>
