Hi Amir,
The floating.pie function (plotrix) might do what you want. For
example:

# first create a simple function to do the chart
sector_col=NULL,main="",xlab="",ylab="") {

nbubbles<-length(xpos)
if(is.null(sector_col)) {
sector_col<-list()
for(scol in 1:nbubbles)
sector_col[[scol]]<-rainbow(length(sectors[[scol]]))
}
plot(0,xlim=xlim,ylim=ylim,type="n",
main=main,xlab=xlab,ylab=ylab)
for(bubble in 1:nbubbles)
floating.pie(xpos=xpos[bubble],ypos=ypos[bubble],
col=sector_col[[bubble]])
}
# set the x positions
xpos<-c(2,4,6,8,10)
# and the y positions
ypos<-c(4,8,6,10,2)
# these are the sector extents of the pies
sectors<-list(1:4,c(5,3,8,6,2),c(3,2,1),c(3,7,5,8),c(2.5,3.7))
# get the plotrix package
library(plotrix)
