title: rbind multiple data frames without typing out all the names of the data frames
body: <p>Have 68 data frames with the same structure and columns. I started to use <code>rbind</code> and after typing in about 30 df names, I thought there might be an easier way to concatenate all the data frames without typing in each name. I mean, what if you have 100,000 data frames to concatenate? I looked at a dozen of online resources including this site and didn't find exactly what I was looking for.</p>
  
  <p>All the 68 data frames are named sequentially. For example: <code>df_01</code>, <code>df_02</code>, ... up to <code>df_68</code>. I tried to do <code>rbind(df_01:df_68)</code> and of course this did not work. </p>
