Why don't the "layout.pos.row" and "layout.pos.col" arguments of ?viewport not do exactly what you appear to want? Perhaps I misunderstand, but I think what you want to do is just create your layout as above and then push the viewports you want by suitably setting these arguments, and then just draw your plots. If you're serious about using grid, Murrell's Graphics book is essential and probably will clarify these issues for you (better than I can, anyway). > > With layout() one can simply cbind/rbind boxes to produce the desired > result.

From ?grid.layout: "This function must NOT be confused with the base R graphics function layout. In particular, do not use layout in combination with Grid graphics. The documentation for layout may provide some useful information and this function should behave identically in comparable situations. The grid.layout function has added the ability to specify a broader range of units for row heights and column widths, and allows for nested layouts (see viewport).
