Hi Marco,
The essence of a pie chart is simplicity. You can do what you want with floating.pie and pie.labels from the plotrix package, but the result may not be as informative as it could be. If you are interested in showing the differences between your quantities, fan.plot is a better bet, although if "many" is more than about ten, you will be stretching that one, too. Bar plots are better at displaying large numbers of quantities, and are usually well tolerated by audiences.
