title: What does NearZeroVar in R?
body: <p>I have rather huge dataset in which I would like to exclude columns with a rather low variance, which is why I would like to use the phrase NearZeroVar. However, I do have some trouble understanding what freqCut and uniqueCut do and how they influence each other. I already read the explanation in R but that does not really help me with this one. 
  If anyone could explain it to me, I would be very thankful! </p>
