  Not at the moment ... you could hack the "piechart" function to do it,
but people here will probably tell you not to, to find another (better)
way to display your data.  If you're desperate I might be able to do it
for you, although not right away.

 As it says in the "piechart" function,


     Pie charts are a very bad way of displaying information. The eye
     is good at judging linear measures and bad at judging relative

     A bar chart or dot chart is a preferable way of displaying this
     type of data.

  Random question to the R cognoscenti: is there a primitive accessible
through R code for drawing arcs and circles?  Except for symbols(), all of
the circle- and ellipse-drawing code I've seen breaks the graphics into a
many-sided polygon ("edges" in piechart()).  This doesn't matter for
bitmap graphics but for vector graphics it might sometimes be nice to have
access to such a function ...
