title: Dividing two data frames by common rows in R
body: <p>I have 2 data sets</p>
  <pre><code>&gt; df2&lt;-data.frame(name=c(&quot;A&quot;,&quot;B&quot;,&quot;C&quot;),F1=c(5,8,9),F2=c(3,8,9),F3=c(1,2,3))
    name F1 F2 F3
  1    A  5  3  1
  2    B  8  8  2
  3    C  9  9  3
  &gt; df1&lt;-data.frame(name=c(&quot;C&quot;,&quot;C&quot;,&quot;A&quot;,&quot;B&quot;),F1=c(1,5,8,9),F2=c(1,5,8,9),F3=c(1,5,8,9))
    name F1 F2 F3
  1    C  1  1  1
  2    C  5  5  5
  3    A  8  8  8
  4    B  9  9  9
  </code></pre>
  <p>I want to divide df1 by df2 by common name ( like C/C, C/C, A/A, B/B). This is only example of my data set which is 250x50.</p>
