title: R Error in .jfindClass(as.character(driverClass)[1]) : class not found
body: <p>trying to install stringi package in R but getting weird error message, below.</p>
  
  <pre><code>Loading required package: DBI

  <p>Looked in other postings but they are all related to DB drivers. No clue what may be causing this in my case, any help appreciated. Many thanks.</p>
  
  <p>Specs: Mac OSX, R Studio, R version is 3.2.0.</p>
  
  <p>UPDATE:</p>
  
  <p>Apparently this issue happens to the installation of other packages too. Below is the output when trying to install DierckxSpline.</p>

  <p>I have no clue so far, and nothing helpful when I Google it. It seems to be a Mac X issue with RStudio. Hope someone can help, thanks.</p>
