Hi, I'd like to produce a marginless or zero margin plot so that the pixel coordinates represent the mathematics.
xy<-data.frame(x=c(0,1,1,0,0),y=c(0,1,0,0,1)) png('junk.png',width=300,height=300) par(mar=c(0,0,0,0)) plot(xy$x,xy$y,xlim=c(0,1),ylim=c(,1)) dev.off() The resultant file has about a 10 pixel margin around these lines, and I'm not sure what parameter or function is controlling this offset. Any hints?
