Dear Ignacio,
if you want it hexagonal (as I gather from the "hexbin_demo", have a look at the
hexbin package.
Otherwise, lattice's levelplot is your friend. Or, if you prefer ggplot:
geom_tile or geom_hex.
UIf you play a bit with findFn from package sos, e.g.
findFn ("plot 2d density")
findFn ("plot 2d histogram")
you'll find more related functions.

I've attached an example about something I want to do in R. This example was
done in a Fortran application called ASGL. Here's an example in matplotlib
http://matplotlib.sourceforge.net/examples/pylab_examples/hexbin_demo.html
Basically, it's like a scatter plot, but have several additional things. One
thing are the grids inside the graph, and the other is a density bar used as a
reference to evaluate the frequency of the points.
The command that I've always used in R for scatter plots is.
> plot(l1, l2)
I need to know if there is something similar in a library of R, or if I could
implement it on my own.
Greetings
Ignacio
