I am saving R graph as a jpeg image and the border is plotted

you open the image.How can I avoid the border?
small R code is as follows :-
volume<- seq(100,10,-10)
jpeg(filename =
"mygraph.jpg",width=366,height=284,units="px")
{
pie(volume,main=title,radius=radius ,bty="n",clockwise =
TRUE,col=color,
font.main = 2,cex.main = 1.8,cex.lab=1.5,border = FALSE)
}
dev.off()
when I open this image automaticaly border is plotted around the
graph.
How to avoid this?
Read the help pages? The pie help page Argument definition for border
refers you to the polygon help page... see that handy little link?
"border
the color to draw the border. The default, NULL, means to use
par("fg"). Use border = NA to omit borders."
I get an error complaining about missing a "color" vector when I try
to test border=NA with your code, but presumably a more complete
example would have demonstrated success. ( I did try putting in
something for col= but then "radius" was also missing so back to you,
booby.)
