To grid, yes, since hexbin is based on grid. E.g.,


grid.newpage()
pushViewport(viewport(layout=grid.layout(2, 3)))

for (k in 1:6) {

  pushViewport(viewport(layout.pos.col = as.integer((k-1) / 2) + 1,
                        layout.pos.row = (k-1) %% 2 + 1))
  plot(hexbin(RG$R[,k],RG$G[,k],xbin=50), ..., newpage = FALSE)
  popViewport(1)

}

There's a lattice version hexbin in the works, but it hasn't been released yet.
