Hi all, I'm trying to use symbols() to draw a circle of a given radius at a given position onto a filled.contour() plot. The commands I issue are:
> filled.contour(y,x,z,levels=seq > (0.02,1.0,len=50),color.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 PS: complete input (5 lines), data file for the contour plot and PDF result on my system can be found at: Data file: http://www.eleves.ens.fr/home/coudert/hist_2d R script: http://www.eleves.ens.fr/home/coudert/hist_2d.R PDF result: http://www.eleves.ens.fr/home/coudert/hist_2d.pdf ______________________________________________ R-help@stat.math.ethz.ch mailing list https://stat.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide http://www.R-project.org/posting-guide.html and provide commented, minimal, self-contained, reproducible code.
