[Bioc-devel] plots and triangle view
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). Kasper On Mon, Dec 3, 2012 at 4:47 AM, Servant Nicolas

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 !
