title: readRDS fails to read in file in R. Is there an alternative?
body: <p>I'm trying to read the RDS file I downloaded from here:</p>
  
  <p><a href="https://github.com/jcheng5/googleCharts/tree/master/inst/examples/bubble" rel="nofollow noreferrer">https://github.com/jcheng5/googleCharts/tree/master/inst/examples/bubble</a></p>
  
  <p>However, when I try to load it into RStudio via:</p>
  
  <pre><code>data&lt;- readRDS('/Users/nathanf/shinyCharts/healthexp.rds')
  </code></pre>
  
  <p>I get the Error: unknown input format.  </p>
  
  <p>I've searched and found a possible solution already posted on StackOverflow, but the solutions mentioned in it do not work.</p>
  
  <p>Does not work:
  <a href="https://stackoverflow.com/questions/6473831/readrdsfile-in-r">readRDS(file) in R</a></p>
  
  <p>Please note, I'm trying to do this with a freshly installed copy of R (3.2.1) on a Mac running Yosemite. </p>
  
  <p>I've found articles online that say the readRDS function is now defunct. <a href="https://stat.ethz.ch/R-manual/R-devel/library/base/html/base-defunct.html" rel="nofollow noreferrer">https://stat.ethz.ch/R-manual/R-devel/library/base/html/base-defunct.html</a></p>
  
  <p>Sooooooo....dearest community, what should I do?  Is there another way to read RDS files using a new function?  </p>
  
  <p>Any help would be much appreciated. </p>
  
  <p>Thank you,
