title: Error: withCallingHandlers crashing R
body: <p>I've been using plyr-based function <code>summarySE</code> and <code>ddply</code> for several months without any problem. Today when I ran my extremely basic routine in R some error message showed up and made R crash.</p>
  
  <p>Here is an example code and the error I get before R crashes: </p>
  
  <pre><code>install.packages("plyr")
  library(plyr)
  results&lt;-data.frame(Depth=rbind("Surface","Bottom"),DO=(runif(10,4,6)))
  ddply(results, .(Depth), summarise,
  mean = round(mean(DO), 2),
  sd = round(sd(DO), 2),
  min = min(DO),
  max = max(DO))
  </code></pre>
  
  <p><code>Error in withCallingHandlers(tryCatch(evalq((function (i):</code><br>
  <code>object '.rcpp_warning_recorder' not found</code></p>
  
  <p>I read that <code>withCallingHandlers</code> is a function to deal with error messages, it shouldn't give me any error during ddply usage. Does anyone know how to fix it?
  I have tried reinstalling <code>plyr</code> but had no success on this issue.<br>
  It was working 14 hours ago, therefore this error makes no sense at all to me...
  Thanks!</p>
  
  <p>Edit: I have also tried to install <code>plyr</code>from the source as suggested <a href="https://stackoverflow.com/questions/19933333/error-thrown-within-ddply-crashes-r">here</a> but it didn't work as well, I still get the same error message.</p>
