grid.grab() does NOT grab a bitmap version of the current picture.  It 
grabs all of the (grid-rendered) grobs in the current picture.  You 
might be thinking of grid.cap(), which is currently only in the 
development version of R.  But if you want a raster version of the 
current plot, it would make more sense to use a raster device, like png().

What I'm interested in doing if I have many pages of plots and I want to keep them together in the same document, say a PDF, is there a way to flatten all the dot plots and graphics, so that they don't take a long time to load on a slow computer in Adobe Reader, without using external programs outside of R ?
