title: R can't write to csv or RData file
body: <p>I'm trying to write the contents of a data frame to an RData file.  </p>
  
  <pre><code>&gt; save(collector2, file="collect2.RData")
  Error in save(collector2, file = "collect2.RData") : 
    error writing to connection
  </code></pre>
  
  <p>As a 2nd option I tried using:</p>
  
  <pre><code>&gt; write.csv(collector2, file="collect2.csv", row.names=FALSE)
  </code></pre>
  
  <p>This executes and creates a file, but it is empty.</p>
  
  <p>Here's the data frame I'm trying to write:</p>
  
  <pre><code>&gt; head(collector2)
            adQuer1     rowid adQueravg
