Hi Milton, The matrix can be generated using
p = matrix(1:50, nrow=5) If I just use levelplot(p), it gives me a graph that is vertical. How can I rotate it so it becomes horizontal? I cannot do q = t(p); levelplot(q) because this is representing a map from a piece of land, transposing the data will flip the map upside down laterally.
