If you want to do this, you need to use grid.

The question is whether it is worth your time, if you're not already
experienced with grid.  Murrell's book is a good place to start (or
the vignettes in grid).

Hi all,

I have 4 matrices that I would like to plot together (as heatmaps)
One way to easily do that is to design a layout (or a grid) and to plot them in each (i,j) cells.

11111222
11111222
11111222
11111222
11111222
33333444
33333444
33333444

But now, I just want to take the same representation, rotate it and only look at the top diagonal data, like this :

       2
     222
    1222
   11222
  111224
 1111244
11111444

For a single matrix, I succeed in plotting this triangle in a cell of a layout, but I failed in plotting all the matrices (i.e., 1, 2, 4) just because I cannot design a grid on this representation.
And to complicate a little bit the problem, I don't want to create a big matrix that combines all matrices, because there are quite big (>3000x3000 each)
I don't know if someone already try to assess this type of issue, or can give some advices about which graphical functions to use (grid, graphics, lattice, ...)
Tank you !
Nicolas
