Draw a circle on a filled.contour() plot
...r.palette=colorRampPalette(c
> ("blue","yellow","red")),title=title(main="",xlab="",ylab=""))
> symbols(0.62,0.0,circles=c(2.5),add=TRUE,inches=FALSE
As can be seen on the resulting PDF file (http://www.eleves.ens.fr/
home/coudert/hist_2d.pdf), the circle appears to have the right
radius but its center is not the correct one [0.62, 0]. What am I
missing here?
Thanks for your help,
FX
