Hi there, I would like to add a few circles to the following image: x<-seq(0,1,0.2) y<-x pred<-matrix(c(0.5, 0.5, 0.5, 0.5, 0.5, 0.5, 0.5, 0.7, 0.7, 0.7, 0.7, 0.5, 0.5, 0.7, 0.9, 0.9, 0.7, 0.5, 0.5, 0.7, 0.9, 0.9, 0.7, 0.5, 0.5, 0.7, 0.7, 0.7, 0.7, 0.5, 0.5, 0.5, 0.5, 0.5, 0.5, 0.5), 6, 6) image(x, y, pred, col = gray(20:100/100), asp='s', axes=F, xlab=" ", ylab="") points(0.5, 0.5, col = 5) # the centre of the image The centre of these circles needs to be overlapped with the centre of the image. Any helps are greatly appreciated.

I ran the three grid.circle commands on my current plot and it did what I expected it to do. It plotted three circles centred in the current viewport. See the jpeg. The last command using points makes me think that you need to understand about units and the setting up of viewports. I have not played around with this much but I think thr newsletter had an article which may be of use (although it uses old code I think the differences are minor) Ciao, Tom -----Original Message----- From: Jin.Li at csiro.au [mailto:Jin.Li at csiro.au] Sent: Monday, 22 November 2004 10:07 AM To: r-help at stat.math.ethz.ch Subject: [R] How to correct this Hi there, I tried to add a few circles on an existing figure using the following codes grid.circle(x=0.5, y=0.5, r=0.1, draw=TRUE, gp=gpar(col=5)) grid.circle(x=0.5, y=0.5, r=0.3, draw=TRUE, gp=gpar(col=5)) grid.circle(x=0.5, y=0.5, r=0.5, draw=TRUE, gp=gpar(col=5)) points(0.5, 0.5, col = 5) # centre of the circle , but all circles moved away from the centre. Could we do any corrections to this? Thanks.
