title: The modules in Revolution R are open sourced. Does the R license imply that I can use the R packages that comes with it free of charge?
body: <p>I noticed that in the library folder of my Revolution R installation that there are some packages unique to Revolution. So I copied them to my regular R distribution and those packages worked fine. </p>
  
  <p>Can I use the Revolution packages free of charge in a commercial environment? My understanding is that anyone who contributes to R needs to make their efforts open source under GPL so anyone can use it and change it in under any setting. Please help me understand this. Thanks</p>
