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.

Re: [R] pie graphic
Hi, I have many data to plot as pie-chart, so the labels are not readable! Is there a way to solve my problem? For example is it possible move the labels more far to the graphic? I'm afraid I can't really answer your question. But in the pie function documentation, you can read the following : , | Pie charts are a very bad way of displaying information. The eye | is good at judging linear measures and bad at judging relative | areas. A bar chart or dot chart is a preferable way of displaying | this type of data. | | Cleveland (1985), page 264: Data that can be shown by pie charts | always can be shown by a dot chart. This means that judgements of | position along a common scale can be made instead of the less | accurate angle judgements. This statement is based on the | empirical investigations of Cleveland and McGill as well as | investigations by perceptual psychologists. ` So an alternative could be to use dotchart() instead of pie().
