title: Use R to translate 'coded' table
body: <p>I have a problem with using <strong>R</strong> to 'translate' back a coded table. So I have a table with table elements consisting of XX,XY,YY. I have a second table (.csv) with the proper meaning of the X and Y - so it might look like, if X=1 and Y=2, </p>
  
  <p>XY is transformed into 12
  XX is transformed into 11 ...</p>
  
  <p>can anybody hint at a good starting point to write such a program/ piece of code in <strong>R</strong>?</p>
