title: cbind dataframes in loop
body: <p>I have <em>n</em> number of dataframes named "s.dfx" where x=1:n. All the dataframes  have 7 columns with different names. Now I want to cbind all the dataframes.</p>
  
  <p>I know the comand</p>
  
  <p>t&lt;-cbind.data.frame(s.df1,s,df2,...,s.dfn)</p>
  
  <p>But I want to optimize and cbind them in a loop, since <em>n</em> is a large number.</p>
  
  <p>I have tried</p>
  
  <p><code>for(t2 in 1:n){
    t&lt;-cbind.data.drame(s.df[t2])
  }</code></p>
  
  <p>But I get this error "Error in <code>[.data.frame</code>(s.df, t2) : undefined columns selected"</p>
  
  <p>Can anyone help?</p>
