title: cbind warnings : row names were found from a short variable and have been discarded
body: <p>I have below line of code for cbind, but I am getting a warning message everytime.
  Though the code still functions as it should be, is there any way to resolve the warning?</p>
  
  <pre><code>dateset = subset(all_data[,c("VAR1","VAR2","VAR3","VAR4","VAR5","RATE1","RATE2","RATE3")])
  dateset = cbind(dateset[c(1,2,3,4,5)],stack(dateset[,-c(1,2,3,4,5)]))
  </code></pre>
  
  <p>Warnings :</p>
  
  <pre><code>Warning message:
     In data.frame(..., check.names = FALSE) :
          row names were found from a short variable and have been discarded
  </code></pre>
  
  <p>Thanks in advance!</p>
