Hi All, simple question:
do you know how to graph the following object/matrix in a 'surface
manner':
[,1] [,2] [,3] [,4] [,5] [,6]
[1,] -0.154 -0.065 0.129 0.637 0.780 0.221
[2,] 0.236 0.580 0.448 0.729 0.859 0.475
[3,] 0.401 0.506 0.310 0.650 0.822 0.448
[4,] 0.548 0.625 0.883 0.825 0.945 0.637
[5,] 0.544 0.746 0.823 0.877 0.861 0.642
[6,] 0.262 0.399 0.432 0.620 0.711 0.404
will be very grateful for hints.

The basic functions you need are image() contour() although I like better the plot.surface() function in the 'fields' package.
