title: precision, recall and f-measure in R
body: <p>I haven't used R in a while, so maybe I'm just not used to it yet, but.. I have a table in R with two colums, the first one has predicted values (a value can be either 0 or 1), the second one has the actual values (also 0 or 1). I need to find recall, precision and f-measures, but cannot find a good function for it in R. (I also read about ROCR, but all I could do was creating some plots, but I really don't need plots, I need the numbers).</p>
  
  <p>Is there any good functions for finding precision, recall and f-measure in R?
  Are there any different ways to do it?</p>
