title: Usage of 'for loop' in R to split a dataframe into several dataframes
body: <p>I have a problem with for loop. 
  I have a dataframe with 120 unique IDs. I want to split the dataframe into 120 different dataframes based on the ID. I split it using the following code:</p>
  
  <pre><code>split_part0 &lt;- split(PART0_DF, PART0_DF$sysid)
  </code></pre>
  
  <p>Now I want to do something like </p>
  
  <pre><code>for(i in 1:120){ 
  sys[i] &lt;- as.data.frame(split_part0[[i]])}
  </code></pre>
  
  <p>This way I have the 120 dataframes with unique frame names I can use for further analysis. 
  Is using 'for loop' in this particular case not possible? If so, what other commands can I use?
  Dummy data for <code>PART0_DF</code>: </p>
  
  <pre><code> Date      sysid   power   temperature
   1.1.2018    1     1000       14
   2.1.2018    1     1200       16
   3.1.2018    1      800       18
   1.1.2018    2     1500        8
   2.1.2018    2      800       18
   3.1.2018    2     1300       11
  </code></pre>
  
  <p>I want the output to be like </p>
  
  <pre><code>     &gt;&gt;sys1
       Date      sysid   power   temperature
       1.1.2018    1     1000     14
       2.1.2018    1     1200     16
       3.1.2018    1      800     18
       &gt;&gt;sys2
       1.1.2018    2     1500      8
       2.1.2018    2      800     18
       3.1.2018    2     1300     11
  </code></pre>
