title: Select seperate objects in R and bind them to one dataframe
body: <p>I was wondering how to select multiple objects in R and save them to a dataframe.
  So let's say <code>ls()</code>gives me following objects:</p>
  <pre><code>ls()
   [1] &quot;[.avector&quot;             &quot;a-32&quot;                  &quot;a-33&quot;                 
   [4] &quot;a_32&quot;                  &quot;a_33&quot;                  &quot;a_34&quot;                 
   [7] &quot;a_35&quot;                  &quot;a_36&quot;                  &quot;a_37&quot;                 
  [10] &quot;a_38&quot;                  &quot;a_39&quot;                  &quot;a_40&quot;                 
  [13] &quot;a_41&quot;                  &quot;a_42&quot;                  &quot;a_43&quot;   
  </code></pre>
  <p>how do connect ls[2:15] to one dataframe?</p>
  <p>Thanks so much in advance!</p>
  <h1>Edit:</h1>
  <p>Following your advice I used this code:</p>
  <pre><code>list&lt;- mget(ls()[2:15])
  df&lt;- do.call(rbind, list)
  </code></pre>
  <p>asking for the class R tells me that df is a matrix.</p>
  <p>so, I converted df to a dataframe yielding this:</p>
  <pre><code>df&lt;- data.frame(df)
  df
  
  data.frame(df)
       X1 X2 X3 X4 X5 X6 X7 X8 X9 X10 X11 X12 X13 X14 X15 X16 X17 X18 X19 X20 X21
  a-32 NA  2 NA NA NA NA NA  4 NA  NA   1   1  NA   6   2  NA  NA  NA   6  NA  NA
  a-33 NA  2 NA NA NA NA NA  4 NA  NA   1   3  NA   6   4  NA  NA  NA   6  NA  NA
  a_32 NA  2 NA NA NA NA NA  4 NA  NA   1   1  NA   6   2  NA  NA  NA   6  NA  NA
  a_33 NA  2 NA NA NA NA NA  4 NA  NA   1   3  NA   6   4  NA  NA  NA   6  NA  NA
  a_34 NA  1 NA NA NA NA NA  1 NA  NA   1   1  NA   4   1  NA  NA  NA   1  NA  NA
  a_35 NA  1 NA NA NA NA NA  4 NA  NA   1   1  NA   6   2  NA  NA  NA   6  NA  NA
  a_36 NA  2 NA NA NA NA NA  4 NA  NA   1   2  NA   6   4  NA  NA  NA   6  NA  NA
  a_37 NA  4 NA NA NA NA NA  3 NA  NA   4   2  NA   6   3  NA  NA  NA   4  NA  NA
  a_38 NA  4 NA NA NA NA NA  5 NA  NA   4   3  NA   6   3  NA  NA  NA   4  NA  N
  .....
  </code></pre>
  <p>So if I see it correctly, R put my objects as rows. Can I bind them to colums?</p>
  <h1>Edit 2:</h1>
  <p>I used cbind() and it worked out. Thank you so, so much for your help!</p>
