Hi seems to me that it can be done by image. See ?image.
Just as illustration. mat<-matrix(sample(c(1,rep(2,10), rep(3,50)), 1000, replace=T), 100,100) for(i in 1:6) mat[i,c(1:(50-5*i),(50+5*i):100)]<-NA for(i in 14:9) mat[i,c(1:(50-5*(15-i)),(50+5*(15-i)):100)]<-NA image(1:100,1:100,mat) HTH Petr On 4 Aug 2006 at 15:12, Gichangi, Anthony wrote: From: "Gichangi, Anthony" <[EMAIL PROTECTED]> To: "R-help" <r-help@stat.math.ethz.ch> Date sent: Fri, 4 Aug 2006 15:12:36 +0200 Subject: [R] plotting picture data > Hi R users > > I have a dataset which represents points that are market by patients > as the source of pain.
