Hi, I am very new to R so I hope this is not stupid. Here a small example: (I use R version 2.13.1) ######################## library("fields") ## round pixel x=matrix(1:100,ncol=10) y=matrix(1:100,ncol=10) for(i in 1:10){ x[i,] <- 1:10 + i y[i,] <- 1:10 + i/20 } #x=1:10 #y=1:10 z=matrix(1:100,ncol=10) pdf("test.pdf") image.plot(x,y,z) dev.off() ######################## With that, the generated pixels have round corners. Uncommenting the second assignements for x and y results in rectangular pixel. For the actual data which I wanted to plot the round corners look much worse. What can I do to get non-round pixels? Thanks a lot! Sebastian -------------- next part -------------- A non-text attachment was scrubbed...
