title: Removing a column whose header is blank from a dataframe
body: <p>I have the following output from a R code:</p>
  
  <pre><code>trans_test11&lt;- as.data.frame(t(test1))
  trans_test11
                (Intercept)   IN_REC_COUNT    THROUGHPUT CPU_USAGE MEMORY_USAGE
  coef(lin_mod)    178.4455 0.000006450854 -0.0006819742 -1.223342     7.275717
                        CAHCE_SIZE
  coef(lin_mod) -0.000000002349061
  </code></pre>
  
  <p>I want to remove the row.names coef(lin_mod) field.
  How can I do that?</p>
  
  <pre><code>The output should like the following:
  
  (Intercept)   IN_REC_COUNT    THROUGHPUT   CPU_USAGE    MEMORY_USAGE    
  178.4455      0.000006450854 -0.0006819742 -1.223342     7.275717
            CAHCE_SIZE
   -0.000000002349061
  </code></pre>
  
  <p>I need this because I need to load the data in a Table in an Oracle DB.</p>
