Change dimension of a data frame
<p>I have a large data frame called "df" (with some NA values inside)</p>

<pre><code>dim(df)
[1] 2174  420    
</code></pre>

<p>I would like to change the dimension of it into 32610 rows and 28 columns (by row), for example:</p>

<pre><code> #df=

  a b c d e f g ...
1 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 ...    
2 .........   
3 .........    
4 .........    
5 .........    
6 .........    
...........
</code></pre>

<p>Into:</p>

<pre><code>#new.df=

  r1 r2 r3 r4 r5 r6 r7 ...                                                   ... r28
1 1  2  3  4  5  6  7  8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28   
2 29 30 ...   
3 .........    
4 .........    
5 .........    
6 .........    
...........
</code></pre>

<p>Therefore, new dimension:</p>

<pre><code>dim(new.df)
[1] 32610  28 
</code></pre>

<p>Can anyone help me with the code?</p>
