search for: cooridn

I wish to draw a graph representing multiple series (sets of x,y points). Each series has its own label and points within each series are joined by a line ordered by their X cooridnate. I would also like a legend automatically showing which each series is. Which high-level command can serve this purpose? I looked at my book but can't find such a command. Thanks! Mark

The filled.contour function gives me some strange output. What did I do wrong? x=seq(0,1,length=10) y=seq(0,1,length=10) z=array(rnorm(100),dim=c(10,10)) filled.contour(x,y,z) lines(0.4,0.8,type="p") abline(v=0.4,lty="dashed") the x-cooridnate of the line and the point is 0.4, but it's slightly above. This problem just appears with "filled.contour", so I guess there is a problem with the key on the right. I use 2.4.0 under unbuntu Thomas
