search for: antidiagonal

Dear list, I have the following matrix. How can I make the following plot? 1. The x-axis has index 1:7, and the first column is plotted against index 1, second against 2, and so on. 2. I want the points from the left upper conner including the antidiagonal to be plotted with col=2, and the rest with col=3 [,1] [,2] [,3] [,4] [,5] [,6] [,7] [1,] 0.589 0.857 0.923 0.944 0.954 0.963 0.980 [2,] 0.470 0.763 0.877 0.900 0.911 0.957 0.974 [3,] 0.486 0.863 0.905 0.960 0.968 0.998 1.015 [4,] 0.653 0.888 0.943 0.952 0.962 0.992 1.009 [5,] 0.664 0.7...

Hola! In the lattice function splom, is it possible to get the tickmarks/value labels _outside_ the scatterplot matrix, and not inside each of the panels in the antidiagonal of panels with variable labels? Kjetil Halvorsen
