Troubles with cell labels in mosaic plots… and how to solve them.

Today I want to write about a solution to a quite specific problem. Suppose, you want to label cells in your 'vcd' package mosaic plots in a custom way. For example, we might want to use cell labels which indicate "too much" or "too few" cases (given your expected values). Such labels might be "+" and "-" (and maybe...
