rotate levelplot
...om left hand corner. My map starts with the (0,0) at the top left hand corner. How can I rotate the map 90 degrees clockwise so the (0,0) starts at the top left? That means I need the 10 columns to be x-axis. I cannot transpose the matrix because the map would be laterally flipped over. levelplot(quadsec.mat, colorkey=list(space="bottom"), scales=list (tick.number=10), aspect=c("iso")) Thanks, I'm ready to give more information if needed.
